Comparative StudyCodeine did not increase analgesic efficacy of coxibs in contrast to that of paracetamol or ibuprofen: isobolographic analysis in mice.
There is good evidence that opioids can potentiate analgesic activity of some older non-opioid analgesics (such as paracetamol or ibuprofen) but it is not known whether this also holds true for newer non-opioid analgesics that selectively inhibit cyclooxygenase 2 (coxibs). This study was undertaken to determine the nature of the interaction between codeine and celecoxib or etoricoxib in peritoneal irritation-induced visceral pain in mice. For comparison, interactions of codeine with paracetamol and ibuprofen were also tested using the same method. ⋯ These and other results suggest that opioids do not seem to potentiate analgesic effects of selective COX-2 inhibitors, in contrast to nonselective COX inhibitors or paracetamol.

Case ReportsTransverse testicular ectopia with abnormal karyotype - a case report.
Growth disturbances and developmental malformations of external genitalia, such as hypospadias, bifid scrotum and micropenis, coexisting with non-palpable testes, may develop as a result of primary endocrinological dysfunctions as well as an effect secondary to chromosomal aberrations. Therefore, patients with these symptoms require specific diagnostic and therapeutic approaches. ⋯ The presence of mosaic karyotype with abnormal Y chromosome does not exclude a possibility of testis migration disorders, including TTE, caused by other (possibly genetic) factors. Laparoscopy is a technique of choice for diagnosis and treatment in cases of cryptorchidism.

Huperzine induces alteration in oxidative balance and antioxidants in a guinea pig model.
Alzheimer's disease (AD) is a neurodegenerative disorder. Symptomatic treatment is available by inhibitors of acetylcholinesterase (AChE) such as rivastigmine, galantamine and donepezil. As huperzine is a promising compound for AD treatment, our study was aimed at evaluating its pertinent implications in oxidative stress. ⋯ We discuss the potency of huperzine in enhancing the antioxidant capacity of the central nervous system. Huperzine is probably implicated in more processes than cholinesterase inhibition only.
