These data show that it is efficacious to give Humalog insulin postprandially in toddlers with type 1 diabetes, allowing increased safety for the young child. The insulin dose can be both matched to the actual food intake and timed to give families increased flexibility and control at mealtime.
Demodex canis infestation in dogs remains one of the main challenges in veterinary dermatology. The exact pathogenesis of canine demodicosis is unknown but an aberration in immune status is considered very significant. No studies have underpinned the nexus between induction of demodicosis and neural immunosuppressive pathways so far. We have evaluated the involvement of cholinergic pathways in association with cytokines regulation as an insight into the immuno-pathogenesis of canine demodicosis in the present study. Remarkable elevations in circulatory immunosuppressive cytokine interleukin-10 and cholinesterase activity were observed in dogs with demodicosis. Simultaneously, remarkable reduction in circulatory pro-inflammatory cytokine tumour necrosis factor-alpha level was observed in dogs with demodicosis. Findings of the present study evidently suggest that Demodex mites might be affecting the cholinergic pathways to induce immunosuppression in their host and then proliferate incessantly in skin microenvironment to cause demodicosis.
In this paper, we described the pharmacological and toxicological studies of three pyrazolone derivatives namely PYZ1: 4-[4-N dimethylamino benzylidine]-3-methyl pyrazolin-5(4H)-one, PYZ2: 4-[2-chlorobenzylidine]-3-methylpyrazolin-5(4H)-one and PYZ3: 4-[benzylidine]-3-methylpyrazolin-5(4H)-one derivatives. Analgesic, anti-inflammatory and antipyretic studies of 3-methyl pyrazolone derivatives at 400 mg/kg, p.o. have shown significant activity as compared to control. Amongst three pyrazolone derivatives, PYZ2 was found to be more active. Based on the result of pharmacological studies, PYZ2 was selected for toxicological studies. Acute toxicity studies revealed that methyl pyrazolone derivatives are non-toxic in rats up to 5000 mg/kg, p.o. The subacute toxicity study of PYZ2 showed that decrease in Hb content, RBC and WBC count. In biochemical analysis level of blood glucose and bilirubin reduced where as AST, ALT and alkaline phosphatase level elevated. Histopathological studies revealed that there was mild toxicity on liver and kidney at 1000 mg/kg, p.o.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
