Anti-genotoxic and free-radical scavenging activities of extracts from (Tunisian) Myrtus communis.

The effect of extracts from leaves of Myrtus communis on the SOS reponse induced by Aflatoxin B1 (AFB1) and Nifuroxazide was investigated in a bacterial assay system, i.e. the SOS chromotest with Escherichia coli PQ37. Aqueous extract, the total flavonoids oligomer fraction (TOF), hexane, chloroform, ethyl acetate and methanol extracts and essential oil obtained from M. communis significantly decreased the SOS response induced by AFB1 (10 microg/assay) and Nifuroxazide (20 microg/assay). Ethyl acetate and methanol extracts showed the strongest inhibition of the induction of the SOS response by the indirectly genotoxic AFB1. The methanol and aqueous extracts exhibited the highest level of protection towards the SOS-induced response by the directly genotoxic Nifuroxazide. In addition to anti-genotoxic activity, the aqueous extract, the TOF, and the ethyl acetate and methanol extracts showed an important free-radical scavenging activity towards the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. These results suggest the future utilization of these extracts as additives in chemoprevention studies.

Reproductive effects in German cockroaches by ecdysteroid agonist RH-0345, juvenile hormone analogue methoprene and carbamate benfuracarb.

Blatta germanica is the more prevalent cockroach species in Algeria. In the present study, we tested the effect on reproduction in B. germanica of two insect growth regulators, RH-0345, a benzoylhydrazine analogue that mimics the action of 20-hydroxyecdysone, and methoprene, one of the most commercially important juvenile hormone analogues, and a novel carbamate insecticide, benfuracarb. The compounds were applied topically (10 and 20 microg/insect for RH-0345, and 1 and 10 microg/insect for methoprene) or orally administrated (at 2% for benfuracarb) on newly emerged females and evaluated on reproductive events during the adult life (2, 4 and 6 days). Treatment with RH-0345 and benfuracarb reduced significantly the number of oocytes, the size and the volume of the basal oocyte during the experimental period. Methoprene distorted the ovarian development since it caused a significant reduction in the number of oocytes at 2, 4 and 6 days for the two tested doses, and an increase in oocyte size at 2, 4 and 6 days with 1 microg and a decrease with 10 microg. In a second series of experiments, the effects of these compounds were assayed on the ovarian proteins. Data from biochemical analysis revealed that RH-0345 and benfuracarb reduced the ovarian amounts of proteins, while treatment with methoprene increased it during the sexual maturation.

[Colloid carcinoma of the prostate].

We report a case of colloid carcinoma of the prostate, a rare tumor type whose diagnosis is exclusively based on the anatomopathological findings. The case described herein is a primary prostatic tumor. Patient work up revealed no tumor localized to other organs. The total acid phosphatase and prostate acid phosphatase levels were elevated. Subsequent analyses revealed metastases.

[Rhabdomyosarcoma of the epididymis].

A 5-year-old boy with intrascrotal rhabdomyosarcoma arising from the epididymis is described. The patient was submitted to radical orchidectomy via the inguinal approach and high ligation of the spermatic cord. The anatomopathological examination revealed germ cell rhabdomyosarcoma of the epididymis with no testicular or spermatic cord involvement, which corresponded to stage I of the IRS classification (Intergroup Rhabdomyosarcoma Study). Its clinical and histological features and treatment are discussed.

[Treatment of hyperlipidaemia. A comparison of the efficacy of clofibrate and beta-pyridylcarbinol (author's transl)].

64 patients with hyperlipidaemia, 13 of them with pure hypercholesterolaemia, were assigned to one of three pre-determined treatment regimes over a period of seven months. Two different commercial preparations of clofibrate and one preparation of beta-pyridylcarbinol were each given for two months separated by placebo periods of two weeks. All three drugs were equally effective against increased cholesterol levels. The two clofibrate preparations lowered increased triglyceride levels more reliably than beta-pyridylcarbinol.
