1. Introduction

 

The modern data of molecular biology and pharmacology regarding the double - way (bidirectional) effects of some chemical mediators and drugs at various doses, the knowledge of special laws of information processing and storage, different from those of the other two forms of manifestation of matter, the substance and energy (Restian, 1981, 1989), as well as our concern for the cybernetic and informational pharmacology (Cristea, 1985, 1991), revealed us a theory which we called the "informational theory of  doses"  (Cristea, 1996).

         In the light of this theory, we endeavoured to systematically develop an " informational pharmacology of dosages " (Cristea, l994; l995). For this purpose we initiated systematic researches on the pharmacodynamic effects of a drug, over a wide scale of dilutions.

         Considering that the informational pharmacology of  concentrations could be a scientific basis of linkage between the allopathic pharmacology and a future homeopathic pharmacology (Cristea, 1994), we concomittantly extended the study also to dilutions prepared according to the dynamization technique by succussion, used in the homeopathic pharmacy (Hahnemann 's technique).

         For the first research, we adopted a classical  pharmacodynamic method, the "in vitro" method which uses isolated organs (Turner, 1965),  taking into account that in the allopathic experimental pharmacology, the isolated organ is acted up on, with high dilutions, situated at the inferior limit of the low homeopathic dilutions.

         The first drug chosen was Belladonna (Cristea et al., 1991), because it is used both in allopathy and in homeopathy. Thus in allopathy, atropina, the alkaloid extracted from Atropa belladonna is known to exert a spasmolytic action and is used in the treatment of colics on the basis of the therapeutic principle of contraries ("Contraria contrariis curentur"). As is known, in homeopathy, the Belladonna tincture at suballopathic dilutions exerts a spastic action and is also indicated at high dilutions in the treatment of colics, but on the basis of another terapeuthic principle,  that of similitude ("Similia similibus curentur").

 

 

 

2. Method

 

1.1. DRUGS AND DILUTIONS

 

The Belladonna (B) tincture (containing 0,03g% total alkaloids, expressed in atropine) was progressively diluted with water, at a geometrical ratio of 1:100. Thus, a scale of centesimal dilutions  (C)  between the first dilution 10-2 (1 C) and the 200th dilution  10-400 (200 C), with a content of 6.023 x 1017 and respectively 6.023 x 10-381 atropine molecules/100 ml, was obtained. The content of moles and atropine molecules/100 ml was calculated for all the 1 C - 200 C dilutions, according to Avogadro's number (6.023 x 1023 molecules/ mol) and taking into account the molecular weight of atropine (MW = 289.41g ~ 300g) (Table 1).

The dilutions were prepared in two ways: a) by simple homogeneization, without succussion (N dilutions) and  b) by "dynamization" with manual succussion  (knocking slightly 100 times the vial against a firm substrate, rhythmically, at a frequency of 1 succussion/second for each dilution), according to Hahnemann's homeopathic technique (D dilutions).

Likewise, D dilutions 1 C - 5 C were prepared in water, starting from distilled water, as well as from alcohol 70°, the solvent with which the Belladonna tincture was prepared. These dilutions were used  as control.

All the D and N solutions were prepared in the Homeopathic pharmacy in Bucharest, especially for this research. The reference substances, atropine sulphate (ATR) and acetylcholine chlorhydrate (ACH), were used in standard  N aqueous solutions, 10-2, with a content of 17.33 x 1018 and respectively 33.55 x 1018 molecules/100 ml.

 

1.2. ANIMALS

 

Male white Wistar rats, with an average weight of 150 g, fasting, with access only to water the day of the experience, were used. They were sacrificed by instantaneous decapitation.

The experiences were carried out in spring and autumn, between 10 h and 16 h.

 

1.3. TECHNIQUE

 

The "in vitro" classical technique on the isolated rat duodenum, mounted in the isolated organ bath  (Turner, 1965), with special precautions for high dilutions, was used.

Duodenum fragments 2 cm long in situ were isolated and immediately mounted in the isolated organ bath containing Tyrode type physiologic salt solution, treated with glucose, regulated thermostatically at 37 °C and oxygenated by air bubbling at a constant output. The motor activity (motility) of the isolated organ, both the normal tone and isotonic contraction was recorded using a classical kimograph.

         The traction (stress) constantly exerted upon the duodenum during the test was of 2 g and the inscription was permanently 10 times amplified.

The accommodation to the in vitro conditions occurred within 10 minutes. The rest interval between two tests was of 5 minutes. On a duodenum fragment was performed two tests. After each test followed the washing of the duodenum (by emptying and refilling the bath with Tyrode's solution), repeated four times. The volume of the solution making the object of the research, dropped with a pipette into the bath, was always of 0.2 ml / 20 ml of bath.

         Separate baths were used for the tests with : Belladonna, 1 C - 9 C dilutions, 10 C - 200 C dilutions, N dilutions, D dilutions and atropine. During a working day, in the same bath, the low solutions were tested in an increasing order of concentrations and the high dilutions were tested at random.

 

 

1.4. TESTS

 

In each test, each dilution of Belladonna (B), as well as the solution of each reference substance, was tested on eight duodenum fragments (n = 8). 

 

 

1.4.1. Testing the effect on the normal tone of the rat duodenum

The action of the test dilution of B, on the normal tone of the isolated rat duodenum, was recorded during 5 minutes. The values of the effects exerted by the B dilutions (tone decrease or increase) were expressed in percentage against the effects (relaxation or contraction) produced by the reference substances atropine sulphate (ATR) and acetylcholine chlorhydrate (ACH) respectively , at the standard dose of 10-6 g/ml of bath.

 

1.4.2. Testing the effect on the  ACH induced spasm

A spasm of the isolated rat duodenum was induced by acethylcholine chlorhydrate (ACH) at the standard dose of 1 mg / ml of bath (10-6 g/ml of bath). Two minutes after the administration of ACH, during the maintenance "en plateau" of the maximum spasm, the test dilution of B was administered and its effect on the spasm was observed for 3 minutes.

         The intensity of the effect exerted by B dilutions (decrease or increase of ACH spasm) was expressed in percentage against the contraction produced by ACH at the standard dose of 10-6 g/ml bath, on the same duodenum .

 

1.4.3. Testing the identity principle ("Aequalia aequalibus curentur")

The identity principle, on which isopathy is based, was tested.

The therapeutic effect of B dilutions, on the relaxation or contraction induced on normal tone by B itself at the dilutions which had an significantly effect on normal tone, namely 1 C - 5 C and 45 C respectively (according to the test described at point  1.4.1.), was studied. The number (%) of appearances of therapeutic effect (determined as the return to the value of normal tone ± 25 %) was established.

 

1.5. STATISTICAL ANALYSIS

 

The statistical significance of the results was calculated by using the Student's "t" and Wilcoxon tests for 1.4.1. and 1.4.2. tests and Chi square test for 1.4.3. test.

From the point of view of scientific requests of the method on the isolated rat duodenum and of statistical tests used, in correlation with the bioethical regulations of research on animals, we established the number of the determinations for each dilution of B, at eight duodenum fragments,  from eight rats (n = 8). 

 

 

3. Results

 

3.1. THE EFFECT OF BELLADONNA (B) DILUTIONS ON THE NORMAL TONE OF THE RAT DUODENUM

 

The effect of  D water was a statistically insignificant rise in the tone. The D aqueous solutions of alcohol 70° had no effect.

The  N aqueous solutions of B had the effect of lowering the normal tone of the isolated rat duodenum, only up to 6 C (unidirectional, monophasic effect) (Figure 1).

The  D dilutions of  B exerted an effect up to 45 C, i.e. relaxation between  1 C-20 C and contraction between  30 C-45 C (bidirectional, biphasic effect) (Figure 1).

At the same degree of dilution, the  D dilutions had a more intense effect than the N solutions (Figure 1). The statistically significant values (p<0.05, at n = 8) are shown in Table 2.

The effect of D water consisted in a slight stimulation and was statistically non-significant. The  D aqueous dilutions of alcohol 70° had no effect.

The N solutions of B had a spasmolytic effect only up to the 9 C dilution, with a content of 6.023 x 102 ATR molecules/100 ml (unidirectional, monophasic effect) (Figure 2).

The D dilutions of B had an effect up to the 200 C, with a content of 6.023 x 10-381  ATR molecules/100 ml. On the scale of D dilutions 1 C - 200 C, the effect had a sinusoidal course, i.e. the decrease of the contraction at the  1 C - 25 C,  55 C - 60 C and 160 C - 200 C dilutions and the increase of the spasm at the  30 C - 50 C and 70 C - 150 C dilutions (bidirectional, multiphasic effect) (Figure 2).

The higher D dilutions were more efficacious. Thus, among the D dilutions which have antagonized the ACH spasm, the highest dilution studied, 200 C, had the most intense effect of 71.12 %. Among the dilutions which have amplified the ACH spasm, the 75 C had the highest effect of 95.45 % (Table 3).

         Conversely, at the N dilutions, the efficacy decreased with the increase of the dilution, hence with the lowering of the concentration.

The statistically significant values (p<0.05, at n = 8) are listed in Table 3.

3.3. THE EFFECT OF BELLADONNA (B) DILUTIONS ACCORDING TO THE IDENTITY PRINCIPLE ("AEQUALIA AEQUALIBUS CURENTUR") USED IN ISOPATHY

 

The N solutions of B had no curative effect, according to the identity principle, on the relaxation induced by the 1 C solution of B.

All the studied D dilutions of B had a therapeutic effect (in all the n = 8 cases), according to the identity principle, both on the relaxation induced by the N or D dilutions 1 C and on the contraction induced by the D dilution 45 C of  B . The prerequisite was to use for the treatment, higher dilutions than the dilution used to induce the imbalance of tonicity. Thus,  B in the D dilutions 5, 45, 75 and 200 C reduced the hypotonia induced by B in the 1 C dilution, both N and D. On the other hand, B in the D dilutions 55, 75 and 200 C diminished the contraction induced by B in the  D dilution 45 C (Figure 3).

 

 

4. Discussion

 

The statistically significant results disclosed quantitative and especially qualitative differences in the pharmacodynamics of the non-dynamized (N) and dynamized (D) preparations according to Hahnemann's technique.

Quantitative differences :

-At the same degree of dilution, the D dilutions had a more intense biological effect than the  N dilutions.

Qualitative differences :

-The  N dilutions exerted a pharmacodynamic action only up to the limit of the molecular specificity, calculated on the basis of Avogadro's number at the 9 C dilution, with a content of  6.023 x 101 molecules/100 ml. 

In contrast with the above, the D dilutions exerted a statistically significant biological effect also at high dilutions, over 10 C, which mathematically and according to Avogadro's number, do no more contain any molecule of the dissolved active substance.

-The N dilutions had unidirectional monophasic pharmacodynamic action on the 1 C-9 C scale.

The action of D dilutions, on the spasm, was bidirectional (double - way) multiphasic, with a sinusoidal course,on the  1 C - 200 C scale (Figure 2).

-Belladonna (B) in  N dilutions  exerted only a relaxant pharmacodynamic action on the duodenal smooth muscle, on the 1 C - 9 C scale, an effect known in the allopathic pharmacology.

In D dilutions, on the 1 C - 200 C scale, B exerted also a contracting pharmacodynamic action on the duodenal smooth muscle, action which in the allopathic pharmacology is unknown for B.

-In N solutions the effect decreases with the increase of the dilution degree and rises with the increase of the concentration and dose.

In D dilutions, the efficacy rises with the increase of the dilution degree.

-Only dynamized (D) dilutions (prepared according to Hahnemann's homeopathic technique) acted according to the identity principle ("Aequalia aequalibus curentur") used in isopathy.

The N solutions acted only according to the principle of contraries ("Contraria contrariis curentur") used in allopathy.

         All these qualitative differences, detected between the N and D preparations, with respect to their biological  effect, can be explained only by admitting that another form of information, qualitatively different from that existing in the N preparations, is also present in the D preparations (Cristea, 1991). The appearance of this new form of information in D dilutions can be due only to dynamization by rhythmical succussions according to Hahnemann's preparation technique.

Since in high D dilutions, exceeding 10 C, the molecule of dissolved active substance is no more present as an informational substrate, according to Avogadro's number, the information in D dilutions should be looked for in another informational substrate : a submolecular structure, a certain form of energy or, merely, a specific molecular organization of the solvent.     

         The clearly superior potency and efficacy of the D preparations demonstrate that the information conveyed by these preparations is much more specific to the living matter. Starting from the hypothesis that according to the laws of information processing and storage, the structural information carried by the active atropine molecule can be conveyed, under certain condition, by the solvent, we performed - concomitantly with the pharmacological study-, a research by physical methods, in order to detect in the solvent, the informational substrate of high B dilutions.

         For this purpose, a calorimetric methodology was used, i.e. the high resolution mixing calorimetry (HRMC) and the differential scanning calorimetry (DSC), the sensitivity and reproductiveness of which in the study of aqueous solutions has been demonstrated on a wide series of cases (Dragan, 1987). The HRMC and DSC experiments disclosed a definite organisation of water in D dilutions, in comparison with N dilutions. Two distinct structures, with a sinusoidal multiphasic course, in accordance with the bidirectional multiphasic pharmacodynamic effects, were observed in D dilutions of B (Cristea et al., 1987; Dragan, 1991).

-A systematic study on bidirectional rhythmic effect phenomenon was made (Husemann, 1992).    

-The results, which we have obtained in calorimetric studies performed on aqueous Belladonna (B) solutions, highly diluted in a centesimal geometric progression on the 1 C - 200 C scale, are consistent also with those of other researchers which were carried out on high dilutions and lead to the same conclusions (Cabaner and Bastide, 1992; Endler and Schulte, 1994).

-The homeopathic drug, characterized by infinitesimal doses and by dynamization according to Hahnemann's preparation technique, has a marked informational character, acting in conformity with one of the laws of information action : "Minimum quantity, maximum significance, maximum effect" (Restian, 1971).
