IDPH-8261--a new nonsteroidal antiinflammatory agent.

IDPH-8261, methyl alpha-methyl-4-(3-thienyl)benzeneacetate, exhibited marked anti-inflammatory activity in acute, subacute and chronic models of inflammation. In rats, IDPH-8261 exhibited a dose related inhibition of carrageenin-induced rat paw edema and the inhibition was greater than ibuprofen, phenylbutazone, but was three times less than indomethacin. It exhibited anti-inflammatory activity in normal and adrenalectomized rats. It also exhibited the activity against various phlogistic agents. IDPH-8261 exhibited AI activity in subacute granuloma tests. In adjuvant-induced established polyarthritis. IDPH-8261 exhibited anti-arthritic effect at a very low dose (ED50 = 4 mg/kg, p.o.). Ulcerogenic liability was the lowest (UD50 = 180 mg/kg, p.o.), when compared to reference standard drugs. Low toxicity and high efficacy may make this compound a potentially useful therapeutic agent.

Prognosis in intra-abdominal sepsis.

Peritonitis is a common surgical problem with a high mortality rate. Recent advances have not brought down the mortality rate. Eighty six patients with intra-abdominal sepsis were studied for factors affecting prognosis. The factors which significantly affected prognosis were: duration of illness, source of infection and APACHE-II score. Further, among the factors contributing to APACHE II score, statistical analysis using logistic regression identified some factors which individually affect outcome. Our results indicate that mortality rate is high in patients with long duration of illness, postoperative peritonitis and organ system insufficiency.

Immunotherapeutic modification by an ayurvedic formulation Septilin.

Effect of Septilin, an ayurvedic formulation proven to be effective in the therapy of chronic infections, was investigated on the phagocytic system and humoral response in rats and mice. Septilin exhibited significant protection in E. coli-induced abdominal sepsis in normal mice and in Staphylococcus aureus-induced sepsis in neutropenic mice. It significantly reduced the viable E. coli cells when incubated with neutrophils in rats. Septilin stimulated the phagocytic function of the reticuloendothelial system in mice. In normal rats, Septilin enhanced anti-SRBC hemagglutination antibody titre by 5.7-fold and showed significant protection in cyclophosphamide-induced humoral suppression.

A rapid method for evaluation of analgesic and anti-inflammatory activity in rats.

Carrageenin (2%) was used to produce edema and hyperalgesia; indomethacin, phenylbutazone, aspirin, ibuprofen, analgin, paracetamol and phenacetin were tested at different doses for anti-inflammatory and analgesic activity in the same rats as the peak for the edema reached at the end of 3rd hr and for the hyperalgesia at the end of 4th hr. Indomethacin, phenylbutazone and ibuprofen reduced edema and increased the pain threshold. Analgin and aspirin increased the pain threshold relatively at a low dose. Paracetamol and phenacetin were inactive in the doses tested. Carrageenin (2%) was observed to possess both phlogistic and allogenic properties.
