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.

Association of Serotype With Antimicrobial Resistance Patterns Among Shigella flexneri Isolates From Pakistan: The Importance of Serotype 2b.

BACKGROUND: Shigella flexneri is an emerging threat in low socioeconomic countries including Pakistan. No previous data is available on the association between S. flexneri serotypes and antimicrobial resistance in Pakistan. OBJECTIVES: The objective of the present study was to assess the association between serotypes and antimicrobial resistance patterns among S. flexneri isolated from clinical and nonclinical samples. METHODS: A total of 199 S. flexneri isolates were subjected to molecular serotyping and antibiotic resistance. RESULTS: The most prevalent S. flexneri serotype was 2b (38%) followed by 1b (24%), 7a (20%), 2a (11%), 1d (5%) and Y (2%). The phylogenetic reconstruction showed 12 clades among which the clades II, III, V, VIII, IX and XI have consisted of serotypes that were found both in human population and environment samples. A high level of multidrug resistance (MDR) was observed in serotype 2b (37.68%) followed by 1b (19.5%) and 7a (19.5%), 2a (11.5%), 1d (5%) and Y (2%). All isolates of serotype 2b showed high level of resistance to amoxicillin/clavulanic acid (100%) followed by quinolone (74.6%) and trimethoprim-sulfamethoxazole (54.6%). Interestingly, none of the serotype was resistant to piperacillin-tazobactam, imipenem and amikacin. The most frequently detected resistance genes among serotype 2b were blaOXA (100%) followed by qnrS (88%), cat (81%) and sul2 (63%). CONCLUSION: The most frequent S. flexneri serotype was 2b while 1d and Y was first time reported in Pakistan. High frequency of MDR serotypes of S. flexneri is a serious threat in diarrhea endemic regions and thus require urgent strategies for its continuous monitoring and prevention.

Prevalence and susceptibility patterns of bacteria causing respiratory tract infections in North Waziristan, Pakistan.

Respiratory tract infections (RTIs) are the most common infectious diseases in humans and are the major cause of mortality and morbidity in Pakistan. These infections are the leading causes of consultations in primary care in Pakistan. Therefore, this study was aimed at determining bacterial pathogens of respiratory tract infections and the susceptibility patterns of bacterial isolates to antibiotics. The study was conducted between February, 2013 and March, 2014 in North Waziristan region of Pakistan. Sputum specimens were collected aseptically from 227 patients and cultured on the appropriate bacteriological media. Bacterial isolates were identified by biochemical tests and their antibiotics susceptibility patterns were determined by standard methods. Out of 227, various species of bacteria were isolated from 152 (75%) specimens. The prevalence of bacteria species isolated were as follows Pseudomonas aeruginosa (42.8%), Streptococcus pneumoniae (26.7%), Corynebacterium diphtheria (10.6%), Staphylococcus aureus (5.9%), Proteus vulgaris (4.6%), Micrococcus species (3.3%), Klebsiella pneumoniae (2.6%) and Bacillus species (2.6%). The susceptibility patterns varied among bacterial species depending on the antibiotics. For the susceptibility test 11 commercially available antibiotics against bacterial isolates were used. The results revealed that generally the bacterial isolates were susceptible to gentamicin (80.9%), meropenem (75 %), ceftazidime (62.5%), cefotaxime (57.9%) and ceftriazone (57.9%) and resistant to penicillin (84.9%) and doxycycline (78.9%). The antibiotics gentamicin (100%) meropenem (100%), ceftriaxone (58.5%), ciprofloxacin (60%) trimethoprim (60%), ceftazidime (66.2%) and cefotaxime (64.6%) were observed effective against the P. aeruginosa isolates. The findings of our study provide significant information for empiric therapy of patients with RTIs in North Waziristan region of Pakistan.

An in-depth review on the medicinal flora Rosmarinus officinalis (Lamiaceae).

Rosmarinus officinalis (Rosemary) is a common household plant which belongs to the family Lamiaceae and is grown in many parts of the world. It is a woody, perennial herb with fragrant, evergreen, needle-like leaves and white, pink, purple or blue flowers. The two most commonly grown hardy Rosemaries are Rosmarinus officinalis 'Arp' and R. officinalis 'Madelene Hill' (syn. 'Hill Hardy'). The other cultivars of the plant are R. officinalis 'Albus', R. officinalis 'Bendenen Blue', R. officinalis 'Goodwin Creek', R. officinalis 'Herb Cottage', R. officinalis 'Logee's Light Blue', R. officinalis 'Miss Jessup's Upright', R. officinalis 'Russian River', R. officinalis 'Salem'. The chemical constituents include bitter principle, resin, tannic acid, volatile oils and fl avonoids. The volatile oil consists of borneol, bornyl acetate, camphene, cineol, pinene and camphor. It is used for problems involved in central nervous system, cardio vascular system, genito urinary conditions, liver treatments, reproductive system and respiratory system. The volatile oil of the plant is used in oils and lotions for the treatment of various ailments like arthritis, gout, muscular pain, neuralgia, wound and rubbed into hair for stimulating the hair bulbs to renewed activity, to prevent premature baldness.

The relationship between moral reasoning, provictim attitudes, and interpersonal aggression among imprisoned young offenders.

This study examined the relationship between moral reasoning, provictim attitudes, and interpersonal aggression among imprisoned young offenders. The participants were 60 imprisoned male young offenders from a young offender institution or remand centre. Using the Direct and Indirect Prisoner Behaviour Checklist, the offenders were categorised as one of four groups: perpetrator, victim, perpetrator-victim, or not involved. Participants in the four groups were compared on measures of provictim attitudes and sociomoral reasoning. The results showed that the majority of the participants were involved in victimising behaviours, with 43.3% falling into the perpetrator-victim category. Victims had significantly more empathic attitudes toward victims than did those in the perpetrator-victim group. No significant differences were found among the four groups on the sociomoral reasoning measure, nor was there a significant correlation between sociomoral reasoning and provictim attitudes. The results are discussed in terms of previous research and their implications for practice.
