Single injection of very mild dose BOTOX in the vastus lateralis improves testicular spermatogenesis and sperm motility in ageing experimental mice

Acetylcholine (ACh), a key neurochemical messenger that plays key roles in neuroplasticity and muscle contraction. While ACh is important for the physiological function of the testis, abnormal levels of ACh cause testicular atrophy and male infertility. BOTOX is a therapeutic form of the botulinum neurotoxin that blocks the excessive release of ACh at the neuromuscular junction. Previously, repeated intracremasteric injections and slight overdose of BOTOX have been reported to induce adverse effects in the testicular parameter of experimental rodents. However, a mild dose of BOTOX is highly beneficial against skin ageing, neurological deficits, overactive urinary bladder problems, testicular pain and erectile dysfunctions. Considering the facts, the possible therapeutic benefit of BOTOX on the testis might be achieved via its minimal dose and indirect mode of action rather than repeated high quantity in the local supply. Therefore, we revisited the effect of BOTOX but with a trace amount injected into the vastus lateralis of the thigh muscle, and analyzed histological parameters of testis and quality of semen in ageing experimental mice. Experimental animals injected with 1 U/kg bodyweight of BOTOX showed enhanced spermatogenesis in associations with increased activities of key antioxidants in the testis, leading to increased total sperm count and motility. This study signifies that a mild intramuscular dose of BOTOX can be considered as a potential treatment strategy to manage and prevent male infertility.

Role of Trospium chloride and tamsulosin therapy for treating patients with symptoms of over-active bladder related to benign prostatic enlargement

To assess the benefit and safety of composite therapy (Tamsulosin and Trospium drugs) in treating benign prostatic enlargement complain, mainly overactive urinary bladder symptoms. OBJECTIVE: The study has been designed to estimate the benefit and safety of Trospium and Tamsulosin in processing of symptoms of excessive bladder and benign prostate hyperplasia (BPH). Patients and Methods: Prospective clinical trial study conducted at Al-Diwaniya teaching hospitals and private clinics from march 2016 to march 2017, to patients BPH and bothersome symptoms. 60 patients were treated with Tamsulocin and 60 patients were treated by Tamsulocin and Trospium. RESULTS: Median scores of IPSS, OABSS, and QOL proved no big difference between two study sets before staring treatment (P = 0.544), (P = 0.287) , (P = 0.668) consecutively. After one month, both treatments led to a big reduction in IPSS, OABSS median score; (P < 0.001), (P < 0.001). Following three months, both treatments resulted in significant reduction in IPSS (P < 0.001), OABSS (P < 0.001), QOL result, (P < 0.001) consecutively. Conclusion: These results suggest which treatment with Trospium and tamsulosin therapy provides benefit for men with natural - Syndrome of the acute urinary tract and benign enlarged prostate.

On the Absolute Stereochemistry of Tolterodine: A Circular Dichroism Study

Tolterodine (1) is a potent muscarinic receptor antagonist used in the treatment of overactive urinary bladder (OAB) syndrome. Tolterodine is chiral and it was patented, and is currently marketed, as the l-tartrate salt of the (R)-enantiomer. However, the existing literature does not offer an ultimate proof of a stereoselective mode of action of 1. A second open stereochemical issue concerns the absolute configuration (AC) of 1. Neither the original patents nor subsequent studies have established the AC of 1 in an unambiguous way, although the AC of the l-tartrate salt of 1 was assigned by X-ray diffractometry. Finally, neither electronic nor vibrational circular dichroism (ECD and VCD) spectra of 1 are reported so far. We performed a thorough ECD/VCD study of 1 in different solvents and at variable temperatures. Solvent and temperature dependence highlighted the existence of moderate flexibility which was confirmed by molecular modelling. ECD calculations with time-dependent density functional theory (TDDFT) accurately reproduced the experimental spectra and allowed us to confirm the AC of 1 in an independent way.
