the chemical nature of secretion by the stigma and transmitting tissue in datura stramoniumwas studied by light microscopy using sudan black b, coomasie brilliant blue (cbb), toluidine blue,safranin, and pas. the stigmatic secretion reacted positively for lipids. during development, stigmaticcells became separated and intracellular lipids were transferred to intercellular spaces where theygradu...

Background: Secretory proteins of IgE receptor activated mast cells and basophils play a pivotal role in the generation of immediate and long term immune responses in allergy and type I hypersensitivity. Objective: The present study aims to generate a 2-D map and profile of proteins secreted from a high secretory variant of the rat basophilic leukemia cell line, RBL-2H3.1, which in view of the ...

Background: Rat prostate gland which is used in various investigation has considerable morphological differences with other mammals. There are few reports about its structure. So, this study was carried on for determining of histomorphological structure of rat prostate. Materials and Methods: Five healthy adult male rats with average weight 20 ± 180 g and approximately 3 - 3.5 months age were s...

background: secretory proteins of ige receptor activated mast cells and basophils play a pivotal role in the generation of immediate and long term immune responses in allergy and type i hypersensitivity. objective: the present study aims to generate a 2-d map and profile of proteins secreted from a high secretory variant of the rat basophilic leukemia cell line, rbl-2h3.1, which in view of the ...

Objective: The present study was aimed to study anti-diarrhoeal activity of a polyherbal formulation (PHF) in rats and elucidate its mechanism of action. Materials and Methods: Anti-diarrhoeal activity of PHF was investigated using castor oil-induced diarrhoea, small intestinal transit and enteropooling models in rats. PHF was tested at 75, 150 and 300 mg...

the present study is related to the histochemical investigations on the changes in the intensity of reactions of axons, acid and neutral mucopolysaccharides, biologically active macromolecules, particularly glycogen and protein component as well as alkaline phosphatase (alpase) and adenosine triphosphatase (atpase) in the cells lining the olfactory epithelium of catla catla . the intense reacti...

Background: Neem leaves (Azadirachta indica L.) have been used for many therapeutic purposes and medicinal applications. The extract of this plant has been used in both male and female genders as a traditional agent to prevent early pregnancy. In this study, the effect of this extract was investigated histologically and morphometrically on the germinal epithelia of the seminiferous tubules, epi...

background: macrophage immune responses are affected by the secretory proteins of mycobacterium tuberculosis (mtb). this study aimed to examine the immune responses of macrophages to mtb secretory antigens, namely esat-6, cfp-10, and esat-6/cfp-10. methods: thp-1 cells (a human monocytic cell line) were cultured and differentiated to macrophages by phorbol 12-myristate 13-acetate. the cytotoxic...

BACKGROUND: In the present study, the submandibularsalivary gland microscopic morphology of the adult Africangiant pouched rat was investigated. This study was carried out toprovide the basic histology of this organ in the giant pouched rat,to accompany the dearth of information of its microscopicarchitecture in the available literature. This becomes of evenhigher importance when considering th...
