Evaluation of Herbal Hair Lotion loaded with Rosemary for Possible Hair Growth in C57BL/6 Mice.

Background: Rosmarinus officinalis (rosemary) is a common household plant with needle-like leaves and white flowers that belongs to the family Lamiaceae and has various medicinal properties including ailments of hair and scalp, cardiovascular, nervous disorders, etc., In the current work, we have focused on formulation and evaluation of 1% hair lotion incorporated with methanolic extract of R. officinalis. Materials and Methods: The aerial parts of the plant were extracted with methanol and then the nature of phytochemicals were identified by chemical tests. It showed the presence of proteins, amino acids, fats and oils, steroids, glycosides, phenolic compounds, flavonoids, volatile oil, and vitamins. The extract was formulated to a suitable hair lotion and then evaluated for its various quality control parameters. Finally, the lotion was evaluated for hair growth promoting activity on C57BL/6 mice, using water as control and 2% minoxidil hair lotion as standard. Results: It was observed that the formulated 1% herbal hair lotion passed all the evaluation parameters and showed a significant hair growth promoting activity than the standard drug-treated animals. Conclusion: Although several researches have been carried out on the rosemary, an investigation on formulation of hair lotion adding the extract of the aerial part of the plant is for the first time. Since our formulation exhibited an excellent activity, it can be well thought out to be an alternative to the commercially available hair growth promoters with a lot of unwanted effects.

Extraction, GC-MS Evaluation and Anti-epileptic Potential of Seeds Ethanolic Extract of Putranjiva roxburghii Wall.

BACKGROUND: Putranjiva roxburghii Wall is traditionally known to cure many pathological conditions including epilepsy. OBJECTIVE: The present study is aimed at determining bioactive compounds in ethanolic extract of Putranjiva roxburghii test extract (PRTE) seeds by GCMS analysis and to assess its antiepileptic potential using various experimental models of epilepsy. METHODS: The ethanolic extract of seeds of Putranjiva roxburghii was subjected to GC-MS analysis to detect the bioactive phytoconstituents. Acute oral toxicity of the extract was performed using OCED guideline 420. Pentylenetetrazol (PTZ) kindling model of epilepsy and Maximal electroshock epilepsy (MES) model of epilepsy were used to determine anti-epileptic potential. RESULTS: The GC-MS analysis of the extract revealed the presence of 20 phytoconstituents. The major phytoconstituents included n-Propyl heptyl ether (25.25%), 5-Ethyl hydantoin (8%), octadec- 9-enoic acid (16.25%) and 1, 2-Benzene dicarboxylic acid (11.86%). The PRTE (50 mg/kg and 100 mg/kg) afforded a significant and dose-dependent protection against PTZ-induced kindling epilepsy and MES induced epilepsy (p<0.001 and p<0.01). CONCLUSION: Based on the above findings, it is evident that Putranjiva roxburghii seeds contain biologically active compounds. It can also be concluded that the extract possesses anti-epileptic potential.

Culture-positive and culture-negative endocarditis in patients with cancer: a retrospective observational study, 1994-2004.

Endocarditis is uncommon in patients with cancer. The characteristics of culture-positive (CPE) and culture-negative endocarditis (CNE) in high-risk cancer patients are not known; therefore we sought to evaluate the disease characteristics in patients with endocarditis at a comprehensive cancer center. We retrospectively reviewed the transthoracic (TTE) and transesophageal (TEE) echocardiograms obtained from 654 consecutive cancer patients in whom endocarditis was suspected between 1994 and 2004. Endocarditis was confirmed in 45 (7%) of 654 patients using modified Duke University criteria based on information obtained from hospital records and computerized data systems. In 21 (95%) of 22 cases, TEE examinations were diagnostic, and 16 (42%) of 38 patients with initially nondiagnostic TTE studies had the diagnosis confirmed by TEE study; this difference between diagnostic TEE and initial nondiagnostic TTE was significant (p < 0.0001). Among the 26 (58%) patients with CPE, Staphylococcus aureus (35%) was the most common organism isolated, followed by coagulase-negative Staphylococcus species (23%). Eighteen (78%) of 23 patients with a central venous catheter had CPE, whereas only 8 (36%) of 22 patients without a central venous catheter had CPE (odds ratio [OR], 6.3; 95% confidence interval [CI], 1.69-23.53; p < 0.006). Vegetations were larger in patients with CPE than in patients with CNE (median +/- standard deviation, 10 +/- 8.8 vs. 8.7 +/- 3.9 mm). Fifteen patients (58%) with CPE and 10 (53%) with CNE had embolic complications. We note that cutaneous and septic pulmonary emboli were more common in patients with CPE than in patients with CNE (31% vs. 11% and 15% vs. 0%, respectively), whereas embolic cerebrovascular and fatal embolic coronary events were more common in patients with CNE than in those with CPE (37% vs. 12% and 21% vs. 0%, respectively; p = 0.026). The 4-week endocarditis-attributable death rate did not differ significantly between the groups (CPE, 15% vs. CNE, 32%; p = 0.28). On stepwise multivariate regression analysis, patients with neutropenia (OR, 22.52; 95% CI, 2.25-225.48; p < 0.008) and those with embolic cerebrovascular events (OR, 17.07; 95% CI, 1.63-178.45; p < 0.01) had an increased probability of death due to endocarditis. The clinical spectrums of CPE and CNE differed in these patients with cancer. In patients with CNE, embolic cerebrovascular and fatal myocardial infarction were relatively common.
