Kamar, "The ameliorative effect of curcumin on cryptorchid and non-cryptorchid testes in induced unilateral cryptorchidism in albino rat: histological evaluation.", Folia morphologica, vol. 80, issue 3, pp. 596-604, 2021. Abstract

BACKGROUND: Cryptorchidism, one or both hidden testes, is the most common abnormality of male sexual development. Subfertility or infertility is associated with both unilateral and bilateral cryptorchidism. In this study, we investigate the possible ameliorative effect of curcumin (Cur) on the induced-unilateral cryptorchidism testicular injury in both cryptorchid (Cryp) and non-cryptorchid (non-Cryp) scrotal testes through histological, immunohistochemical and morphometrics.

MATERIALS AND METHODS: Forty adult male albino rats were divided into: control group, Cur control group, Cryp group, and Cryp+Cur group. The rat model was surgically established by fixing the left testis in the abdomen. The treated groups were subjected to surgically induced-unilateral cryptorchidism on the left side then were given Cur (80 mg/kg) orally, for 20 days. Histological analysis using haematoxylin and eosin and periodic acid Schiff's reaction was done. Immunohistochemistry was performed for proliferating cell nuclear antigen (PCNA); to estimate the proliferation in the germinal epithelium, and vimentin; to evaluate Sertoli cells. The results were confirmed by statistical evaluation of the spermatogenic epithelium height, the seminiferous tubules diameter, the basement membrane thickness, the number of PCNA immunostained cells and the area per cent of vimentin immunostaining.

RESULTS: Distorted seminiferous tubules, substantial degeneration of the germinal epithelium, thickening of the basement membrane with a significant decrease in PCNA and vimentin immunostaining were observed in Cryp group; mainly in the cryptorchid testis. These structural changes were significantly reversed in Crypt+Cur group.

CONCLUSIONS: Curcumin proved to be an important and effective medical line for protecting against the unfavourable sequels of cryptorchidism in a rat model.

Abdallah, M. A., T. A. Farghaly, and M. A. M. A. andZienab Muhammad, "Anti-Alzheimer Activity of Novel 1,3,4-Thiadiazole Derivatives", World journal of chemistry, vol. 6, issue 2, pp. 96-106, 2011. AbstractCU-PDF.pdf

The reaction of the new enaminone 2 with ?-ketohydrazonoyl chlorides 3 afforded 5-(pyrazol-4-yl)-carbonyl-2-benzoylimino-1,3,4-thiadiazoles 5. Treatment of 5a with hydrazine hydrate led to formation of pyrazolo[3,4-d]pyridazine derivatives 8. The reaction of enaminone 2 with 6-amino-2-thioxopyrimidin-4-one 9 in acetic acid under reflux produced 2-thioxopyridopyrimidinone derivative 10. The latter compound or its methylthio derivative 15 reacts with hydrazonoyl chlorides 3 to give pyridotriazolopyrimidine derivatives 14. The newly synthesized compounds 2, 5, 8 and 14 were tested for their anti-alzheimer activity, and the results which obtained revealed their potency as drugs for Alzheimer disease.
