The aim of this study was to determine the application of mixed cultures Candida lipolytica and Candida tropicalis in the SCP production. N-paraffin fraction of crude oil and individual n-alkanes C:7--C:17 and glucose were used as carbon sources. The cultures were grown on laboratory scale in shaking flasks and in a 7 1 fermentor. It was found that the mixed cultures gave about 18% higher yield of biomass than the individual cultures.

Oxotremorine did not alter the level of 5-HT and 5-hydroxyindoleacetic acid in different brain regions. The content of 5-HT in the striatum was diminished by electrolytic lesions of the raphe system, by microinjection of the selective depletor 5,6-dihydroxytryptamine into the raphe system and inhibition of synthesis by pCPA or pCAM. The intensity of oxotremorine-induced tremor was reduced only in some experimental groups without clear-cut correlation to the decreased 5-HT levels. In pCPA-pretreated animals resoring of 5-HT concentration by intrastriatal microinjection of 5-HT and ip administration of 5-HT did not reestablish tremor intensity. There is no evidence that cholinergic tremor is triggered indirectly and depends upon an intact 5-HT system.

Two new compounds: 2- and 4-pyridylmethylamides of acetyltropic acid (PAT 2 and PAT-4) show spasmolytic effects on isolated guinea pig ileum, have mydriatic actevity in rabbits and block restraint produced ulceration in rats. PAT-4 causes a strong inhibition of the salivary secretion in mice. Both of the test compounds inhibit also the effects of ACh and vagus stimulation on the blood pressure and have local anaesthetic activity. PAT-4 inhibits the aggressive behaviour in mice and rats, prolongs the hexobarbital sleeping time, increases the pain treshold and inhibits the oxotremorine induced tremor in mice. Both PAT-2 and PAT-4 had no effect on the convulsant action of pentetrazole. EEG findings show that central cholinolytic activity is present in both compound tested.

Three patients of different ages with evidence of essential tremor of familial origin are reported. Pneumoencephalography demonstrated in these cases presence of hydrocephalus. The size of the cerebral ventricles was assessed by means of the index of Schiermann and Evans. No correlation was observed between the degree of changes in the ventricular system and the duration of the disease. Abnormalities moencephalograms concerned only the Evans index.

The effect of etorphine on dopamine and noradrenaline concentrations in different central nervous system structures in the rat. Acta Physiol. Pol., 1977, 28 (6): 529-540. Intramuscular administration of etorphine in immobilizing doses (0.008 mg/kg) was followed by a rise in dopamine concentration in the examined motor structures of the central nervous system (striopallidum, pons, cerebellum, lumbosacral intumescence of the spinal cord). Only in the motor centres of the frontal cortex dropamine concentration was decreased. At the time etorphine decreased the concentration of noradrenaline in striopallidum and raised it in the other examined structures of the central nervous system. A correlation was found between the concentrations of both substances, especially in the frontal motor centres and striopallidum. Post etorphine accumulation of dopamine in the striopallidum (for 6.369 to 11.322 mcg/g of fresh tissue) with simultaneous inhibition of motor activity of the animals suggests that etorphine inhibits the release of dopamine from the presynaptic elements in the motor centres of the central nervous system in rats. This leads to a decreased dopamine action on its receptors. Some post etorphine behavioral changes (rigidity, spastic flexion, muscle tremor) support this hypothesis.

On the basis of the concepts connecting parkinsonian tremor with reduced amount of serotonin in the striatum and in the light of the hypothesis of an agonistic action of pizotifen in relation to serotonin a trial was undertaken to reduce parkinsonian tremor in 12 patients administering Sandomigran in daily doses of 1.5 mg. A significant reduction of tremor was achieved in two-thirds of these patients. No side effects or increased intensity of other parkinsonian signs were observed.

The effect of chlorophenothane (pp'--DDT) and five structurally related compounds op-DDD (op'-DDD, pp'-DDD, DTE, DCMP and DCP see text) on the cerebral hemisphere gamma-aminobutyric acid (GABA), the main inhibitory transmitter in brain contents and possible correlation with central activities was demonstrated in rats. The tested compounds were given in oral doses of 600 mg/kg in peanut oil. Cerebral GABA content was determined 1, 3 and 6 hrs after the ingestion of pp'-DDT and 3 hrs after each of the other drugs. The mean GABA content in each group of rats was compared with control groups, either without any treatment, or receiving the equivalent volume of peanut oil. pp'-DDT produced a significant reduction in brain GABA contents 3 and 6 hrs after its administration. This was accompanied by excitability, tremor and clonic convulsions. Of the congenors, only DTE exerted a similar effect. The present results point to the possibility of partial involvement of GABA in the tremor and convulsions induced by pp'-DDT. They also indicate the importance of the CCl2 grouping in the molecule for the induction of central effects of pp'-DDT.

Coretal -- an agent blocking the beta-adrenergic receptors -- was given to 12 patients with Parkinson's syndrome with evident tremor and to 4 patients with benign essential tremor. In the group of Parkinson's syndrome the effectiveness of this treatment was evaluated by the blind method. The whole period of observation was 6 weeks, during 3 weeks the patients received Coretal 60-120 mg daily, during the next 3 weeks they were given placebo. The intensity of tremor was assessed by means of a scoring system. Improvement was achieved in 7 patients with Parkinson's syndrome and in 3 out of 4 cases of idiopathic tremor. Complete disappearance of tremor was never observed. Transient side effects were observed in 2 causes. The authors think that Coretal may be used with good result in treatment of parkinsonian tremor and benign essential tremor.

In 38 patients with Parkinson's syndrome Madopar preparation was used (L-dopa with peripheral decarboxylase inhibitor) in 33 cases as the main drug and in 5 cases as an addition to L-dopa. In the group of 33 patients 39 could complete the treatment, one patient died suddenly, three had the treatment withdrawn in view of side effects. The effectiveness of Madopar was assessed by means of five-rate scoring systems NUDS and ART. Clinical improvement was found in 22 cases (about 67%). The improvement included mainly bradykinesia and rigidity, while tremor was only slightly improved. Side effects developed in about 40% of patients and were slight and transient (apart from 3 cases). The main contraindications seem to be psychotic disturbances. In the group of 5 cases treated with Madopar as an additional drug in low doses improved the result of long-term treatment with L-dopa.

Bilateral injection of 6-hydroxy-dopamine (6-OH-DA) (8mug/4mul) into the substantia nigra causes a significant decrease of the dopamine content in the nucleus caudatus. The intraventricular application of 6-OH-DA (250 mug/10 mul) induces a considerable decrease of dopamine in the caudate nucleus as well as in the globus pallidus and in the medial septal region. Simultaneous changes in norepinephrine content are less spezific. It has to be assumed that there are dopaminergic nerve endings in the glubus pallidus not originating in the substantia nigra. Only after intraventricular applications of 6-OH-DA s short-term and reversible reduction of oxotremorin-induced tremor has been observed. Lesions of the nigrostriatal pathway cause an impairment of motility, probably elicited by rigidity and akinesia. These symptoms correlate better than the tremor to biochemical changes following nigro-striatal pathway lesions.
