Effect of morphine on PHA-stimulated human lymphocyte transformation.

In vitro effect of DDS on phytohaemagglutinin (PHA)--induced lymphocyte transformation.

A study to find out the in vitro effect of diamino diphenyl sulphone (DDS) on phytohaemagglutinin (PHA)-induced lymphocyte transformation was carried out in three phases using a wide range of DDS concentrations. Lymphocytes from healthy volunteers were investigated. Volunteers were divided into three groups to conduct the study in three phases. In each phase in addition to 0.02 ml of PHA, 4 dif...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Effect of ciprofloxacin on mitogen-stimulated lymphocyte proliferation.

Ciprofloxacin was tested for its inhibitory or stimulatory effects on concanavalin A- and phytohemagglutinin-stimulated proliferation (measured by [3H]thymidine uptake) of human peripheral blood mononuclear cells and murine splenocytes. Ciprofloxacin did not diminish or enhance mononuclear cell proliferation at concentrations of 5 to 125 micrograms/ml. Further, the proliferative response of spl...

[Effects of asbestos on the cell cycle of PHA-stimulated human peripheral blood lymphocytes].

It is well known that persons exposed to asbestos display systemic immunological alterations: impaired lymphocyte response to PHA, the appearance of autoantibodies and elevation of the serum immunoglobulin level. The authors intend in this report to determine whether asbestos fibres (crocidolite, chrysotile and amosite) have any effect on the cell cycle of human lymphocytes after PHA stimulatio...
