Histopathological and Enzyme-histochemical Changes after Brain Compression

Early Enzyme Histochemical Changes following Transection of Dorsal Spinal Funiculi.

Histochemical studies of early changes of lactic dehydrogenase activity were done in transected fast. gracilis and cuneatus of cats, to elucidate the significance of the proximo-distal increase in this enzyme normally found in the terminal portions of these tracts. A rapid and uniform loss of activity in the distal portion of transected tracts favors the concept that the gradient of enzyme acti...

Hepatic Histopathological and Histochemical Changes in Mice Infected with Schistosoma Mansoni After Vaccination with Gamma Radiation - Attenuated Schistosomules

Current strategies for the control of schistosomiasis are based primarily on chemotherapy but successful vaccination against infection has been also demonstrated in several host parasitic models. The present study was designed to assess the effect of vaccination with schistosomulae atte nuated by different doses of γ-radiation in mice challenged with S. mansoni cercariae regarding hepatic histo...

Histochemical changes in neocortex and corpus callosum after intracranial injection.

Morphine sulphate induced histopathological and histochemical changes in the rat liver.

In this study, the histopathological and histochemical changes due to chronic usage of morphine sulphate in liver were assessed in rats with both light and electron microscopes. Twenty male albino rats (Rattus norvegicus) (130-150 g) were included and divided into four groups. Normal saline (5 ml) was given orally as placebo in the control group (N=5). Morphine groups (N=5) received morphine or...

Enzyme-histochemical and morphological characteristics of fast- and slow-twitch skeletal muscle after brain infarction in the rat.

The right middle cerebral artery was permanently occluded in 12-week-old male spontaneously hypertensive rats. After the surgery the rats were subjected to repeated behavioural tests during the observation period. Fourteen weeks after surgery the fast-twitch extensor digitorum longus (EDL) and the slow-twitch soleus muscle of both sides were removed and examined with regard to muscle fibre char...
