Thirty of 200 ewes died or were euthanatized during a 21-day period following a 1-day accidental exposure to natural gas condensate, a complex mixture of hydrocarbons obtained during collection of natural gas from wells. Despite access to potable well water, the poisoned ewes willingly consumed toxic doses of condensate that contaminated surface water. Eight animals died without premonitory signs; the remainder became ill over the course of a few days to 3 weeks. The principal cause of mortality was aspiration pneumonia, but myocardial degeneration and necrosis, renal tubular damage, gastritis, enteritis, and meningeal edema and hyperemia were also observed. Gas chromatographic analysis identified chemical traces of the hydrocarbons in the tissues, and "fingerprinting," the process of matching chromatographic tracings, provided forensic proof of the contamination source. Atomic absorption spectroscopy and cholinesterase analyses were performed to eliminate the possibility of toxicosis by heavy metal contaminants or other constituents. This appears to be the first reported incidence of natural gas condensate toxicity involving sheep or other ruminants. Although the available literature presents a suggestive pattern of clinical signs and pathologic lesions of petroleum product poisoning, diagnostic investigations should employ detailed analytic examination because each source of petroleum hydrocarbons contains unique sets of components that may produce different toxic effects.

According to "Spleen-Stomach" theory, the effect of Jianpi Yiqi prescription (JPYQ) was observed clinically and studied experimentally. 168 cases manifested as Spleen-Qi ( ) deficiency including chronic gastritis and peptic ulcer (84 cases), chronic glomerulonephritis (44 cases) and vomitus gravidarum-edema of pregnancy (40 cases) were treated with JPYQ. Estimation were made based on their clinical conditions. Serum gastrin, serum cholyglycine, blood acetylcholine and cholinesterase, blood 5-HT and histamine were measured before and after treatment. The overall effective rate was 92.9% in gastritis and peptic ulcer group, 86.3% in nephritis group and 100% in pregnancy group respectively. A marked increase of serum glycocholic acid level was shown in gastritis and peptic ulcer and vomitus gravidarum groups. That was considered as the result of the secretion of cholic acid by this prescription. Clinical improvement was also obtained in nephritis group accompanying disappearance of albuminuria in 36.4%. Blood level of 5-HT and histamine lowered to some extent and tended to be normal. Besides, this prescription markedly inhibited electric stimulated excitement on isolated longitudinal muscle strip of guinea pig's ileum. The mechanism could be the inhibition of release of acetylcholine from Auerbach's plexus by this prescription.
