The effect of an ethanol extract of Commiphora myrrha oleo-gum resin on hematological and pathophysiological parameters of male Wistar rats was examined. The extract was given daily for 2 w at 1000 mg/kg bw per os, 500 mg/kg bw i.m. or 250 mg/kg bw i.p. Depression, huddling together, soft feces, jaundice, ruffled hair, hepatonephropathy, hemorrhagic myositis and patchy peritonitis (at the injection site) and death were accompanied by increases in serum ALP and ALT activities, bilirubin, cholesterol and creatinine concentrations, and decreases in total protein and albumin levels, and macrocytic anemia and leucopenia. When administered at 500 mg extract/kg bw/d per os or 250 mg extract/kg bw/d i.m. for 2 w it was not lethal, and when given daily for 1 w the effect was less marked.

Absidiosis was produced experimentally in 18 buffalo calves by intravenous inoculation of spores of Absidia corymbifera. Infected animals exhibited dullness, depression, partial anorexia and an initial pyrexia and coughing during the first week and two animals died on each of 9, 13 and 16 days post infection (DPI). The haemoglobin concentration and total erythrocyte count showed no appreciable change from their basal values at any stage of the experiment. However, the erythrocyte sedimentation rate and total leukocyte count increased significantly in the infected animals. The differential leukocyte count revealed a relative neutrophilia from 5 to 20 DPI. There was a significant increase in the serum total proteins, blood urea nitrogen, creatinine, alanine aminotransferase, aspartate aminotransferase, serum alkaline phosphatase, total immunoglobulins and circulating immune complexes in the infected animals as compared to the controls. In the sera of the infected animals, specific Absidia corymbifera IgM and IgG antibodies were detected from 3 DPI to 6 DPI respectively by Dot-EIA. Type I and type III skin hypersensitivity were detected from 10 DPI and type IV hypersensitivity from 15 DPI onwards. The gross and microscopic pathological lesions were seen mainly in the lungs, in all except one of the affected animals. This animal died 9 DPI and mycotic granulomas were also seen in its heart and kidneys. The microscopic lesions in the lung took the form of well-developed granulomas.

Due to the limited efficacy of alpha-interferon for chronic hepatitis C amantadine has been proposed as a possible alternative method of treatment. However, few studies about efficacy of amantadine in chronic hepatitis C are available with controversial results. Stimulated by recent data in the literature, we studied the effect of 100 mg of amantadine HCL (alone) PO bid, for a four month period on alanine aminotransferase serum levels and viral load in a cohort of 18 patients (14 males and 4 females) with chronic hepatitis C, non-responders to alpha-interferon. Inclusion criteria were: detectable serum HCV-RNA, alanine aminotransferase above the upper limit of normal, chronic inflammation on liver biopsy, no other associated chronic liver disease and written informed consent. Available biopsies showed initially four cases of cirrhosis, six of chronic persistent hepatitis and eight of chronic active hepatitis. The most prevalent HCV genotypes were 3a (n = 9, 52.94%) and 1b (n = 6, 32.29%). Viral load (Amplicor HCV Monitor, Roche, USA) and alanine aminotransferase levels were obtained at baseline and after four months of treatment. All patients enrolled into the study but one completed the treatment. One patient discontinued amantadine due to severe depression. No significant reduction was observed between baseline and final values of alanine aminotransferase (139.118 +/- 79.789 vs. 99.588 +/- 62.583 U/L, P = 0.059) and viral load (7.154 +/- 1.596 vs. 6.574 +/- 1.584 log copies/mL, P = 0.147). Amantadine alone was not effective neither eradicating viremia nor normalizing alanine aminotransferase levels in chronic hepatitis C non-responders to alpha-interferon patients. It is suggested that only a study with amantadine alone in-patients without previous treatments could determine its efficacy in comparison with alpha-interferon.

A toxicity study was made on Lepidium sativum L. seeds used in Saudi traditional medicine for the treatment of various ailments. Lepidium sativum L. seed fed to Wistar albino rats at 2% (w/w) was non-toxic, Ten percent (w/w) was toxic but not fatal and 50% (w/w) of the diet for 6 weeks was lethal and caused depression in growth rate and entero-hepato-nephrotoxicity. Organ lesions accompanied by anemia and leukopenia were correlated with alterations in serum AST and ALT activities and concentrations of total protein, cholesterol, urea, and other serum constituents.

Some haematological and biochemical parameters were studied in guinea-pigs infected intraperitoneally with Salmonella dublin 493 at 1 x 10(6) viable cells per animal. The infected animals showed a rise in temperature within 24 h, followed by depression and loss of body weight. On the 15th day post infection, haematological studies revealed a significant increase in the total leukocyte count due to both lymphocytosis and neutrophilia, and a decrease in the total erythrocyte count and haemoglobin concentration. There was also a significantly higher mean corpuscular volume and lower mean corpuscular haemoglobin concentration, indicating a macrocytic hypochromic anaemia. The infection caused a significant increase in alanine aminotransferase activity and creatinine, blood urea nitrogen and globulin concentrations, and a decrease in albumin and triiodothyronine. There was no significant effect on serum total protein or on thyroxine, or in the activity of aspartate aminotransferase in the serum.

Alcoholism is a very important cause of congestive cardiomyopathy in man. The aim of this study was to examine a short-term effect of ethanol in rat cardiac muscle, using histologic, morphometric and biochemical methods. Experiments were carried out in Wistar male albino rats, divided into two groups: the control group consisting of eight animals receiving tap water, and the experimental group comprising eight animals received ethyl alcohol for ten days, in a single daily dose of 3 g ethanol/kg body weight, per os, using esophageal intubation. The mean volume weighted nuclear volume of cardiac myocytes was estimated by point sampled intercept method, by objective x 100. The mean cubed nuclear intercept length was multiplied by pi and divided by 3. For biochemical analysis, a 10% water tissue homogenate from the left ventricle was made. In the experimental group, the mean volume-weighted nuclear volume (15.08 +/- 5.20 microm3) was significantly lower than in the control group (51.32 +/- 7.83 microm3) (p < 0.001). The treatment of experimental animals with ethanol caused significant increase of aldolase (p < 0.0001) and aspartate transaminase (p < 0.05) activity in the rat cardiac tissue; at the same time, the enzyme activity of creatine phosphokinase, alanine transaminase and alkaline phosphatase were not changed in the experimental group compared to the control values. The amount of the glucose in the cardiac muscle was greater in the experimental group compared to the control animals. Our results suggest that there is depression of cardiomyocyte nuclei in experimental animals treated with ethanol. Alcohol intake results in the loss of Krebs cycle enzymes and as a consequence there is greater utilization of fatty acids for energy production.

The role of glutamate transporters in the regulation of synaptic depression was examined in the avian nucleus magnocellularis. Repetitive stimulation of presynaptic auditory nerve fibers resulted in acute depression of EPSCs. Pharmacological blockade of glutamate transport in glial cells enhanced residual glutamate in the synaptic cleft and markedly increased the extent of depression at stimulus frequencies above 20 Hz via a postsynaptic mechanism. Glutamate pyruvate transaminase, a glutamate scavenger, accelerated the decay of the EPSC and reduced synaptic depression, indicating that transporters are not completely effective in rapid removal of glutamate. Regulation of residual transmitter by glia may thus serve to control synaptic strength in a frequency-dependent manner.

The antioxidant action of Artemisia campestris was examined in vitro and in vivo. A water extract of A. campestris showed a strong scavenging action of 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl and superoxide anion radicals. When the extract was given intraperitoneally to mice prior to carbon tetrachloride (CCl4) treatment, CCl4-induced liver toxicity, as seen by an elevation of serum aspartate aminotransferase and alanine aminotransferase activities, was significantly reduced. Depression of the elevation of serum enzyme levels after CCl4-treatment was also observed by oral administration of the extract. In that case, CCl4-derived lipid peroxidation in the liver was decreased by the extract treatment. These results suggest that the extract of A. campestris scavenges radicals formed by CCl4 treatment resulting in protection against CCl4-induced liver toxicity.

Artemisia abyssinica leaves, a traditional medicine for the treatment of various disorders, were fed to male Wistar rats at 2% and 10% of the standard diet for 6 weeks. A 2% A. abyssinica leaf diet was not toxic to rats. Depression in growth, hepatopathy and nephropathy were observed in rats fed a diet containing 10% of A. abyssinica leaves. These findings were accompanied by leukopenia, anaemia and alterations of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) activities with changes in concentrations of total protein, albumin, cholesterol and urea.

As an antidepressant, bupropion is considered to be a safe agent that usually causes infrequent and mild increase of serum liver enzymes. Asymptomatic elevation of serum transaminases was previously reported only in a single case. We describe a patient who developed typical acute hepatitis after receiving six weeks of bupropion for depression. His presentation was characterized with acute onset of symptoms associated with significantly elevated ALT, AST, and LDH and acute hepatic inflammation. The clinical course of our patient, including incubation period, pattern of liver enzyme elevation, and time of recovery, was similar to, but much more severe than, the case reported by Oslin and Duffy. Discontinuation of bupropion was followed by a rapid resolution of clinical symptoms and liver enzymes. The incidence of bupropion-induced hepatitis remains to be defined even though it appears to be relatively low. Since the clinical application of bupropion is broader, we must be aware of the clinical entity of bupropion-induced hepatitis.
