A series of novel benzohydrazide derivatives containing dihydropyrazoles have been synthesized as potential epidermal growth factor receptor (EGFR) kinase inhibitors and their biological activities as potential antiproliferative agents have been evaluated. Among these compounds, compound H20 exhibited the most potent antiproliferative activity against four cancer cell line variants (A549, MCF-7...

Five mongrel dogs were sensitized to tuberculoprotein with Freund adjuvant, as determined by responses to tuberculin skin tests and by in vitro lymphocyte cultures. These animals served as blood donors for production of transfer factor. Nine mongrel dogs received single doses of transfer factor that was tuberculin specific. Successful transfer of tuberculin sensitivity as measured by lymphocyte...

BACKGROUND Interstitial cystitis (IC) is a chronic bladder disorder of unknown etiology. Antiproliferative factor (APF), a peptide found in the urine of IC patients, has previously been shown to decrease incorporation of thymidine by normal bladder epithelial cells. This study was performed to determine the effect of APF on the cell cycle of bladder epithelial cells so as to better understand i...

The in vitro production of interleukin-1 in 15 children with acute hepatitis A and five children with acute hepatitis B was determined by measuring lymphocyte activating factor secreted by peripheral blood monocytes in a thymocyte proliferation assay. Aluminium hydroxide induced production of lymphocyte activating factor was significantly lower in patients with acute hepatitis A as well as pati...

The purpose of this study was to determine changes in hematological and plasma indices of Common Carp Cyprinus carpio with regard to age, sex and hormonal treatment. Sixty fish were used to assess the age factor. Also, 20 fish including female and male were assigned to determine blood indices with regard to sex and hormonal treatment. The pituitary gland extract was used as hormone for males an...

A unique glycopeptide, antiproliferative factor (APF), has been suggested as a urinary biomarker and potential mediator of long-term bladder disorder Interstitial Cystitis/Painful Bladder Syndrome. There is no known cause for this disease. Several mechanistic approaches have been employed to address the underlying mechanism whereby APF regulates cellular responses in the bladder epithelium. A s...

sensitivity to P.P.D. (Field and Caspary, 1971a) yet negative Mantoux reaction also has a high level of serum depressive factor. The inhibitory factor is not specific, in so far as M.S. or sarcoid serum will also interfere with unrelated antigen-lympho-cyte interaction. For example, serum (1:60) from a patient with other neurological disease and two M.S. sera reduced a mixed lymphocyte reaction...
