A controlled clinical trial comparing 2-Mercapto-Priopionyl-Glycine (2-MPG) plus B12 vitamin with B12 vitamin alone in chronic liver disease has been conducted in seven hospitals in Italy. Patients were divided into two groups on the basis of liver histology; group I included 26 patients showing histological evidence for chronic persistent hepatitis (C.P.H.) (according to De Groote et al.) whereas group II consisted of 54 patients with chronic aggressive hepatitis (C.A.H.) or compensated liver cirrhosis. Patients of each group were randomly allocated to 2-MPG plus B12 vitamin, or to placebo plus B12 vitamin, in a double-blind way. The drug (or placebo) was diluted in 500 ml of 10% Levulose, and administered intravenously; 1000 gamma of B12 vitamin were added to each bottle. Patients in the 2-MPG group received 2.5 gms of the drug daily; the treatment lasted for 30 days. The following parameters were checked in all patients on admission, and repeated at the end of treatment: Serum bilirubin, serum Cholesterol, A.P., BSP retention, Prothrombin time, S-GOT, S-GPT, Gamma-GT, Total serum Protein, serum electrophoresis, Immunoglobulins. Patients given 2-MPG showed significant decreases of serum transaminases, and improvement of BSP retention.

A comparative study of the hepatoprotective effect of carnosine and 4-methyluracil under CCl4-induced acute toxic hepatitis has been carried out. The extent of liver injury and its regeneration were established from morphological data as well as from changes in the activities of alanine aminotransferase (ALT) and histidase and the bilirubin content in blood serum. Hyperlipoperoxidation in the liver and serum was assessed by the amount of TBA-active products. It was found that by day 10 of experimental hepatitis ALT and histidase levels in blood sera of untreated animals exceeded the normal values 1.3- and 3.9-fold, whereas those in the carnosine-treated group approximated the values characteristic of intact animals. The activity of serum ALT in animals treated with vitamin B12 or 4-methyluracil exceeded normal values 1.5 and 1.6 times, whereas that of histidase was 2.5 and 2.7 times as high. Carnosine and 4-methyluracil inhibited (in approximately the same degree) the formation of TBA-active products in the liver. According to morphological dta, cessation of CCl4 injections was accompanied by rapid regeneration of liver tissues in all animal groups. Carnosine enhanced regenerative processes in parenchymatous and connective tissues in a far greater degree in comparison with other drugs. The mitotic index in the carnosine-treated group exceeded more than twofold the corresponding parameters in untreated animals. Possible mechanisms of carnosine action on liver repair are discussed.

Blood serum free vitamin B12, bilirubin, alanine aminotransferase levels were measured and thymol test made in 168 patients with viral hepatitis A, 13 with chronic hepatitis, 8 with mechanical jaundice of neoplastic origin, 7 with calculous cholecystitis, and 8 with functional hyperbilirubinemia by the microbiologic methods. Elevated blood serum levels of free vitamin B12, conforming to the disease severity and stage, were revealed in the patients with viral hepatitis A, chronic active hepatitis, and mechanical jaundice of a neoplastic origin with liver involvement. Correlations between cobalaminemia and other functional liver tests were observed. Therefore blood serum vitamin B12 measurements may be used for the assessment of the disease activity and severity of liver parenchyma injury.

The serum unsaturated vitamin B12-binding capacity (UBBC), unsaturated transcobalamin (UTC) I, UTC II, UTC III levels, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase activities and bilirubin concentration were estimated in 61 patients with liver diseases (31 with hepatoma, 30 with viral hepatitis). The levels of serum cobalamin, UTC I, UTC III, UBBC, alanine and aspartate aminotransferases, and bilirubin were raised in both hepatoma and viral hepatitis patients. Serum UTC II was reduced in both conditions. Alkaline phosphatase activity was significantly increased in hepatoma. Four significant correlations were observed among these parameters in the hepatoma patients while only one significant correlation was observed in viral hepatitis.

Partial ileal bypass (PIB) surgery is a method for the treatment of familial hypercholesterolaemia in man. Since the rabbit is frequently used as an animal model in experimental studies on PIB, we have investigated the long-term effects of this surgical procedure on the health status of rabbits. Forty-eight weeks after surgery plasma and liver cholesterol levels were decreased by about 40%. The inner diameter of the bypassed ileum was drastically reduced, unlike its length. The bypassed segment did not show clear histological abnormalities. The microflora of the caecum was similar in control and PIB rabbits. PIB did not influence liver histology. The bile of the rabbits with PIB was less lithogenic than that of control animals. Blood haemoglobin levels, haematocrit values and plasma concentrations of alkaline phosphatase, alanine aminotransferase, gamma-glutamyl transferase and lactate dehydrogenase were not changed after PIB. Plasma levels of albumin, creatinine, calcium, phosphorus, vitamin B12 and folic acid were not significantly affected by PIB. Rabbits with PIB had significantly higher plasma levels of bilirubin and zinc than control rabbits, but plasma vitamin E concentrations were significantly lower. These results may be of importance for further studies on the effects of PIB in rabbits.

31 healthy Thai males, 22 Thai male regular drinkers not suffering from any clinical signs or symptoms of alcoholism, and 52 patients from a neurological hospital in Bangkok suffering from the effects of chronic alcohol consumption were investigated. Alcohol consumption in asymptomatic drinkers ranged from 7 to 134 (median 44) g/d ethanol, and for the patients 22 to 517 (median 197) g/d ethanol, as assessed by questionnaires. The symptomatic alcohol drinkers had consumed alcohol for 2 to 35 years and the hospitalized patients for 5 to 40 years. Only the median levels of serum triglycerides and serum glutamyl transferase (gamma-G) were significantly increased and vitamin B1 deficiency was found with higher frequency in the group of alcohol drinkers without clinical signs compared with the healthy non-alcohol drinkers. Statistically significant correlations were demonstrated in the group of asymptomatic alcohol drinkers only, between alcohol consumption and the Quetelet's index, gamma-G, and alkaline phosphatase levels. Alkaline phosphatase also correlated significantly with gamma-G. In the group of hospitalized patients, compared with healthy males statistically significantly higher median values of systolic and diastolic blood pressure, serum triglyceride, gamma-G, aspartate aminotransferase (GOT), alanine aminotransferase (GPT), alkaline phosphatase, haemoglobin, hematocrit, folate and total protein were found. The median levels of cholesterol, bilirubin, vitamin B2, B6 and B12 in the hospitalized group were lower than, but not significantly different from the other two groups.

Antitoxic properties of cobamamide, a coenzymic form of vitamin B12, were studied in experimental toxic hepatitis induced by CCl4. The data obtained as a result of the assessment of the bromosulfalene test and activity of sorbitol dehydrogenase and alanine aminotransferase point to a demonstrable hepatoprotective action of cobamamide. Normalization of the indicators studied evidences that the drug intensifies the recovery processes occurring in the liver of rabbits with toxic hepatitis.

The microbiological method was used in 168 virus hepatitis patients aged 16-55 years to study the content of unbound vitamin B12 in the blood serum over the time of the disease before administration of cyanocobalamin and in the course of its application in a dose of 100 and 200 micrograms intramuscularly every other day for 3-4 weeks. In the acute stage of the disease, the patients showed an appreciable hypercyanocobalaminemia that correlated well with the disease severity and with the magnitudes of liver function tests. Cyanocobalamin administered to the patients intramuscularly in a dose of 100 micrograms every other day exerted a more remarkable normalizing effect on the level of unbound vitamin B12, bilirubin, the thymol test, aldolase and alanine aminotransferase of the blood as compared to that produced by the drug injected in a dose of 200 micrograms.

The efficacy of r-interferon alpha 2a (IFM) versus acyclovir (ACV) and vitamin therapy in the treatment of herpes zoster is reported. A total of 305 patients were randomly divided into 3 groups. One million units of IFN were administered i.n. once a day for 6 days in 223 cases, oral ACV 200 mg five times daily for 7 days in 34 cases, and vitamin B12, B1 and B2 therapy at conventional doses for 7-14 days in 48 cases. The results showed that both IFN and ACV could reduce pain in patients with herpes zoster and cut the total duration of symptoms, in comparison with vitamin therapy (P < 0.01). In the IFN group, 45 patients (20.2%) experienced side effects, including mild fever in 35 cases (15.7%) and a slightly depressed leukocyte count or increased serum ALT level (3 cases each). In the ACV group, one complained of discomfort in the gastroenteric tract, and another patient reported lumbodynia.

Two cases of alcoholic cerebellar degeneration with pyramidal sign were reported. Patient 1 with alcohol dependence syndrome was a 46-year-old woman. After the alcohol abuse of about eight years, she complained of gait disturbance. The gait disturbance progressively worsened in about two months and she could not ambulate freely by herself. Neurological examination revealed nystagmus, ataxic and spastic gait, slight weakness and spasticity of the lower extremities, hyperreflexia of the extremities, bilateral Babinski's signs, and incoordination of the lower extremities. Examination of liver function and serum B12 was normal. Cranial CT scan and MRI revealed atrophy of the cerebellar vermis and dorsal part of the cerebellum. Though neurological signs slightly improved after the admission to our hospital and the abstinence from alcohol abuse, ataxic gait and hyperreflexia of the extremities have continued. Patient 2 was a 58-year-old man. He was a heavy drinker, but was not a patient with alcohol dependence syndrome. After the heavy drinking of about 40 years, he complained of gait disturbance. The gait disturbance had progressively worsened in about four months. Neurological examination revealed ataxic gait, hyperreflexia of the lower extremities, and bilateral Babinski's signs. Laboratory examination revealed slight liver dysfunction with minimal GPT and moderate gamma-GTP elevation. Examination of serum B12 was normal. Cranial CT scan and MRI revealed atrophy of the cerebellar vermis. Though bilateral Babinski's signs disappeared after the abstinence from heavy drinking, ataxic gait and hyperreflexia of the lower extremities have continued. Alcoholic myelopathy without hepatic cirrhosis was rarely reported. In the relation of alcoholic cerebellar degeneration to alcoholic myelopathy, our cases are interesting and important.
