Anti-inflammatory, analgesic and antiproteolytic activities of some novel thiadiazoles.

Eighteen novel acetyl salicyloyl/butyroyl mercapto 1,3,4-thiadiazoles have been synthesized and characterized by their elemental analyses, IR and PMR spectral studies. Their efficacy against carrageenin induced paw oedema was tested in albino rats of either sex at a dose of 100 mg/kg p.o. In vitro antiproteolytic activity of the compounds was assessed by determining their ability to inhibit trypsin induced hydrolysis of bovine serum albumin. Active anti-inflammatory compounds were tested for their analgesic activity against aconitine induced writhing in albino mice. Approximate LD50 values were also determined in albino mice.

Antiinflammatory and antiproteolytic activities of newer indolyl isoquinolines.

Several indolyl isoquinoline derivatives were synthesized and evaluated for their antiinflammatory and antiproteolytic activities. These derivatives possessed 9.2-32.4% inhibition at a dose of 100 mg/kg i.p. against carrageenin-induced oedema. Four of these derivatives (IVb, IVd, IVe and IVk) exhibited high potency in inhibiting oedema. The degree of inhibition of trypsin-induced hydrolysis of bovine serum albumin, in vitro, by compounds IVb, IVd, IVe, IVi, IVj, IVk and IVl ranged from 10-42% at a final concentration of 1 mmol/l. In addition, these agents exhibited relatively non-toxic nature and their approx. LD50 was greater than 1000 mg/kg i.p.

Life-threatening acute systemic lupus erythematosus: survival after multiple extracorporeal modalities: a place for the multipotential extracorporeal service.

Diffuse alveolar hemorrhage secondary to systemic lupus erythematosus (SLE) may cause life-threatening respiratory failure and may be associated with multiple organ failure. Extensive support may be necessary to sustain life while systemic therapy becomes effective. We report here a patient with profound respiratory failure secondary to SLE associated with multiorgan failure, who was supported with veno-arterial extracorporeal lung assist (ECLA), veno-venous ECLA, and multiple continuous renal replacement therapies during plasmapheresis. The full spectrum of extracorporeal life support and treatment modalities was performed seamlessly by a single service within the critical care department.

Achalasia cardia: A study of 113 patients managed with indigenous dilator.

BACKGROUND: Endoscopic dilatation of achalasia cardia is an effective nonsurgical management option. It requires costly pneumatic dilators which are used under fluoroscopic guidance. This study assesses the efficacy and safety of an indigenous pneumatic dilator used without fluoroscopic guidance. METHODS: Over a period of eleven years, 113 patients (69M, 44F) ofachalasia cardia underwent dilatation with indigenous pneumatic dilators without fluoroscopic guidance. The dilatation was performed under endoscopic vision. RESULTS: The procedure was successful in all patients. After six weeks following dilatation, there was significant improvement in the mean dysphagia score 3.63 + 0.61 to 0.53 + 0.93 (P<0.01). The response was still significant (0.78 + 1.03, P <0.05) at the end of one year. Excellent response with single dilatation was seen in 70.7% patients. After two dilatation sessions 92% of patients showed an excellent response. One patient had perforation. There was no mortality. CONCLUSION: Pneumatic dilatation under endoscopic vision without fluoroscopic assistance with the indigenous dilator is very effective and safe for short term treatment of achalasia carida.
