The cockroach allatostatin receptor (Dippu-AstR) is a 425 amino acid G-protein coupled receptor that is related to the mammalian galanin receptor. Using relative standard curve real-time PCR analysis, changes in Dippu-AstR mRNA expression levels were examined in tissues of adult mated and virgin female Diploptera punctata. Tissues were chosen that were either known targets of allatostatin (Dippu-AST) action or sites of Dippu-AST localization. Tissues examined included brain, corpora allata (CA), gut, ovaries, testes and abdominal ganglia. Dippu-AstR was expressed in all tissues examined for 7 days after adult emergence. Juvenile hormone (JH) biosynthesis is known to peak on day 5 post-emergence in mated females. In mated females, Dippu-AstR mRNA was at the highest levels on day 6 post-emergence in brain and CA and day 2 post-emergence in midgut. Dippu-AstR expression was found to correlate with the decline in JH biosynthesis noted on day 5 post-emergence and early inhibition of feeding. Dippu-AstR mRNA expression in virgin female midgut and CA was dramatically elevated on days 6 and 7, respectively. Expression of Dippu-AstR mRNA was found to be similar in the abdominal ganglia of mated or virgin females. Ovarian Dippu-AstR expression declined to low levels by day 4. Testes exhibited maximal Dippu-AstR mRNA expression on days 4 and 7 of adult life. A role for Dippu-AST in testes of Diploptera is unknown.

Phyllanthus niruri extract is extensively used in treating liver ailments. Effects of aqueous extract of P. niruri on liver, kidney and testes of CCl4 induced hepatotoxic rats were studied. High levels of malondialdehyde (MDA) were observed in the CCl4 test group with significant reduction of MDA levels in all groups on P. niruri extract administration. Highest levels of glutathione (GSH) were found in P. niruri group. Activities of alanine transaminase, aspartate transaminase and alkaline phosphatase enzymes were significantly reduced in the curative group (P. niruri treatment after CCl4 injection). Histopathology of liver showed lesser degree of inflammation in all P. niruri treated groups while the renal and seminiferous tubules showed eosinophilic protein casts with signs of tubular damage and degeneration. Testes also showed decreased amount of mature spermatozoa. The results suggest that P. niruri has anti-oxidant and hepato-protective activity with associated deleterious effects on kidney and testes.
