Abstract Background Androgenetic alopecia (AGA) is the commonest cause of hair loss in men with limited treatment options. Platelet-rich plasma (PRP) is defined as an autologous concentration of plasma with a greater count of platelets than that of whole blood. Its action depends on the released growth factors from platelets. It has been investigated and used in numerous fields of medicine. Recently, PRP has received growing attention as a potential therapeutic tool for hair loss. Aim of the work This study aimed at evaluating the efficacy of PRP therapy on experimentally induced AGA in male albino rats. Materials and Methods Eighteen rats were divided into 3 groups - Group I (the control group), Group II (testosterone group): rats were injected 0.1 ml testosterone daily in the shaved area of the dorsum , Group III (PRP group): rats were injected 0.1 ml of testosterone daily+ 0.1 ml of PRP every 3 days in the shaved area of their dorsum. After 21 days from the start of the experiment, skin samples were collected from the site of injection and prepared for histological examination by hematoxylin and eosin stain and immunohistochemical examination by anti Ki 67. Morphometrical and statistical analysis were performed. Results Testosterone group when compared to the control group showed a significant decrease in the mean epidermal thickness, decreased mean number of anagen hair follicles, increase in the mean number of telogen hair follicles and decreased anagen/telogen ratio, all were statistically significant (P < 0.05). PRP group showed significant increase in the mean number of anagen hair follicles (p < 0.05), and a decrease in the mean number of telogen hair follicles (p < 0.05). This resulted in an increase in anagen/telogen ratio. There was also a significant increase in the mean epidermal thickness in the PRP group as compared to the other groups (p < 0.05). Immunohistochemical examination of anti Ki 67 stained sections showed significant decrease of the mean number of Ki 67 positive basal epidermal cells (P < 0.05) in the testosterone group compared to control group, and an increase in the mean number of Ki 67 positive basal epidermal cells in the PRP group (p < 0.05) as compared to the control group and the testosterone group. Conclusion Our data suggest that PRP injections may have a positive therapeutic effect on experimentally induced androgenic alopecia in adult male albino rats.

To investigate the safety and clinical efficacy of AA-PRP injections for pattern hair loss. AA-PRP, prepared from a small volume of blood, was injected on half of the selected patients’ scalps with pattern hair loss. The other half was treated with placebo. Three treatments were given for each patient, with intervals of 1 month. The endpoints were hair re-growth, hair dystrophy as measured by dermoscopy, burning or itching sensation, and cell proliferation as measured by Ki-67 evaluation. At the end of the 3 cycles of treatment, the patients presented clinical improvement in the mean number of hairs, with a mean increase of 18.0 hairs in the target area, and a mean increase in total hair density of 27.7 ( number of hairs/cm2) compared with baseline values. Microscopic evaluation showed the increase of epidermis thickness and of the number of hair follicles two weeks after the last AA-PRP treatment compared to baseline value (P<0.05). We also observed an increase of Ki67+keratinocytes of epidermis and of hair follicular bulge cells and a slight increase of small blood vessels around hair follicles in the treated skin compared to baseline (P<0.05).

Background: The prevalence of myocardial infarction (MI) is increasing day by day in Bangladesh due to socioeconomic transition. Spices and herbs are important source of remedy for various diseases in human. Curcuma longa suggested to be used as an indigenous medicine for the prevention and treatment of cardiovascular disease. Objective: To observe the effect of Curcuma longa in isoproterenol induced myocardial infarction in Wistar albino rats. Methods: This experimental study was carried out in the Department of Physiology, Dhaka Medical College, Dhaka during 2015. Twenty one Wistar albino male rats, weighing 100 to 150 g (initial body weight); aged 85 to 100 days were selected for the study. After acclimatization for 14 days, the rats were divided into BC (Baseline control group), ISP-TC (Isoproterenol treated control group) and CLP-ISPT (Curcuma longa pretreated and isoproterenol treated group). Each group consisted of 7 rats. After experiment, on the 10th day, final body weight was taken, rats were sacrificed and blood samples were collected from the heart. The heart was removed and weighed. Serum creatine kinase-MB (CK-MB) level was estimated by ELISA method and Troponin I (cTnI) level by AxSYM method. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Results: In this study, the mean percent (%) change of body weight (p<0.01), mean serum CK-MB (p<0.001) and cTnI (p<0.001) levels were significantly higher but mean heart weight was non significantly higher in ISP-TC in comparison to those of BC. Again, the mean percent (%) change of body weight (p<0.01), mean heart weight (p<0.01), mean serum CK-MB (p<0.01) and cTnI (p<0.001) levels were significantly lower in CLP-ISPT than those of ISP-TC group. Conclusion: From the results, it can be concluded that Curcuma longa may have cardioprotective effect. J Bangladesh Soc Physiol. 2018, December; 13(2): 47-53

Abstract Background Although some studies in the literature report that autologous and homologous platelet-rich plasma (PRP) can be employed in the treatment of androgenic alopecia (AGA), no study, to the authors’ knowledge, has examined the estrogen concentration of prepared PRP. Objectives The authors aimed to determine the presence of estrogen in PRP and to investigate the effect of estrogen concentration of PRP on AGA treatment. Methods Between 2017 and 2018, 30 male patients with hair loss complaints were included in this prospective study. Autologous PRP was injected in patients in Group 1. Homologous PRP with high estrogen levels was injected in the patients in Group 2. PRP was injected in both groups 4 times at 0, 1, 3, and 6 months. The obtained photographs were evaluated and hair densities of each patient at controls were calculated. Results The mean estrogen level measured in PRP was statistically significantly higher in Group 2. In both groups, the increase in hair density was observed from the first month, but this increase was statistically significantly higher in all controls in Group 2. In Group 2, there was a statistically significant increase in the 1st and 3rd months compared with the previous control, but there was no difference between the 6th and 12th months and the 3rd month. Conclusions Increased hair density is greater and earlier in the group receiving estrogen-rich PRP than in the group utilizing autologous PRP. The authors think that estrogen-rich PRP may be employed in the treatment of AGA in the presence of an appropriate donor. Level of Evidence: 2

<p>Chemotherapy-induced alopecia affects the pathological as well as the psychological aspects of the cancer patient. In the present study, the protective role of Nigella sativa was evaluated in both adult and newborn albino rats. The anagen phase was first induced. N. sativa oil, N. sativa decoction (5%, 10% and 15%) and minoxidil lotion (standard) were applied daily to the rats two days after the depilation. During the anagen VI phase of the hair follicles, alopecia was induced by giving cyclophosphamide 125 mg/kg, ip to the adult rat and 50 mg/kg to the newborn rats. Cyclophosphamide-induced the alopecia to the whole depilated area of skin in adult rat while alopecia totalis was observed in the newborn rat disease control group. N. sativa oil, N. sativa decoction (5%) showed a significant protective effect against cyclophosphamide-induced alopecia. In conclusion, it is evident that N. sativa provides significant protection against chemotherapy-induced alopecia.</p><p><strong>Video Clip of Methodology</strong>:</p><p>1 min 43 sec:   <a href="https://www.youtube.com/v/AKhk27V3juE">Full Screen</a>   <a href="https://www.youtube.com/watch?v=AKhk27V3juE">Alternate</a></p>

Background: Ultraviolet B exposure is one of the causes of extrinsic skin aging. Ultraviolet exposure may lead to skin collagen damage. This study about mesenchymal stem cells from umbilical cord (UCMSC) compared with platelet rich plasma (PRP) with the aim was to prove that the intradermal injection of UCMSC was more effective than PRP in increasing amount of collagen and fibroblasts in Wistar rats' back skin exposed to Ultraviolet B rays. Methods: This study used post-test only control group design. Subjects were 36 Wistar rats aged 2.5 months. A control group consisting of 18 Wistar rats treated with intradermal injection of PRP and the treatment group with UCMSC. Both groups were exposed to UVB with a total radiation dose of 840 mJ/cm2. The parameter of collagen was determined by picro sirius red staining while fibroblasts by Haematoxylin-Eosin staining. Result: The mean amount of collagen in the control group was lower (57,82±6.52%) than the treatment group (65.69±4.51%) with p<0.001. The result showed there were differences in the number of collagen in both groups (p<0.05). The mean number of fibroblasts in the control group was lower (22.63±5.98 cell/field of view) than the treatment group (28.20±8.90 cell/field of view) with p=0.034. The result showed there were differences in mean of fibroblasts in both groups (p<0.05). Conclusion: It can be concluded that the intradermal injection of UCMSC was more effective in increasing the amount of collagen and fibroblasts than intradermal injection of PRP in Wistar rats' back skin exposed to UVB rays.

Abstract Introduction Osteoarthritis (OA) is a common health problem. Platelet-rich plasma (PRP) has been recognized to enhance articular cartilage metabolism. Aim of the work the study was designed to investigate the influence of PRP on cartilage healing after induction of arthritis. Material and methods Forty two adult male albino rats were used in this study. The rats were randomly divided into three groups: Group I (n = 18): the control group (Ia, Ib & Ic) Ib & Ic were injected intra-articularly with saline and left for 3 and 6 weeks. Group II (n = 12): arthritic group, in which osteoarthritis was induced by injection of 0.02ml 5% formaldehyde once in the right knee joints, left without treatment, and were sacrificed after three weeks (IIa) or after six weeks (IIb). Group III(n = 12): arthritis was induced as group II, one week later, the rats were intra-articularly injected with single dose of 0.3ml PRP in the same joint then were sacrificed three weeks (IIIa) or six weeks (IIIb) after formaldehyde injection. At the end of the study the right knee joints were taken, decalcified then processed for paraffin sections to be examined by light microscope using H&E, toluidine blue and Masson’s trichrome (MTC) stains. Immunohistochemistry for caspase-3 enzyme was done to demonstrate apoptotic chondrocytes. Morphometric study was conducted to measure the thickness of the non-calcified cartilage, count the chondrocytes and synovial membrane inflammatory cells and Mankin's score. Then statistical analysis was done. Results The arthritic groups revealed irregular surface of the articular cartilage, loss of the articular matrix and bone eburnation. Moreover, there was apparent hypocellularity and disorganization of the chondrocytes. Osteoclasts and osteoblasts were seen invading the osteochondral junction. MTC stained sections of the synovial membrane showed deposition of thick collagen bundles with heavy inflammatory cell infiltrate and numerous blood vessels. The affinity of the articular cartilage to toluidine blue stain was apparently decreased while caspase-3 immunoreactivity was apparent in many chondrocytes .Group IIIa demonstrated almost similar histological findings as the control group; regular articular cartilage surface with regularly arranged chondrocytes in the different cartilage zones. Synovial membrane illustrated minimal inflammatory cell infiltrate with thin collagen bundles and small blood vessels in MTC stained sections. There was high affinity of the articular cartilage to the toluidine blue stain and few chondrocytes showed positive caspase-3 immunoreactivity. Group IIIb revealed continuous surface of the articular cartilage, yet with minimal fibrillation in some areas. Osteoblasts and osteoclasts were seen invading the calcified cartilage. Synovial membrane showed deposition of dense collagen bundles with some inflammatory cell infiltrate. Toluidine blue sections revealed decreased articular cartilage affinity to the stain while caspase-3 immunoreactivity was evident in many chondrocytes. The morphometric results and statistical analysis confirmed the histological findings. Conclusion Intra-articular injection of PRP demonstrated advantageous role on articular cartilage healing, however, these effects appeared to be transient. So the need of multiple injections of PRP has to be considered in cases of OA.

The proprietary DA-5512 formulation comprises six herbal extracts from traditional oriental plants historically associated with therapeutic and other applications related to hair. Here, we investigated the effects of DA-5512 on the proliferation of human dermal papilla cells (hDPCs) in vitro and on hair growth in C57BL/6 mice and conducted a clinical study to evaluate the efficacy and safety of DA-5512. DA-5512 significantly enhanced the viability of hDPCs in a dose-dependent manner (p<0.05), and 100 ppm of DA-5512 and 1 μM minoxidil (MXD) significantly increased the number of Ki-67-positive cells, compared with the control group (p<0.05). MXD (3%) and DA-5512 (1%, 5%) significantly stimulated hair growth and increased the number and length of hair follicles (HFs) versus the controls (each p<0.05). The groups treated with DA-5512 exhibited hair growth comparable to that induced by MXD. In clinical study, we detected a statistically significant increase in the efficacy of DA-5512 after 16 weeks compared with the groups treated with placebo or 3% MXD (p<0.05). In conclusion, DA-5512 might promote hair growth and enhance hair health and can therefore be considered an effective option for treating hair loss.

This study investigated the effects of administration of monosodium L-glutamate (MSG) on serum gonadotrophin-releasing hormone (GnRH), luteinising hormone (LH), testosterone and total cholesterol (TC), cauda epididymal sperm reserves (CESR) and testicular histomorphology of adult male albino rats. Eighty-four rats, randomly assigned to 7 groups of 12 rats each, were used for the study. Varying low doses (0.25, 0.50 or 1.00 g/kg body weight) of MSG were administered orally or subcutaneously at 48-h intervals for six weeks. Serum GnRH, LH, testosterone and TC, and CESR were evaluated on days 14, 28 and 42 of MSG administration. Testicular histomorphology was evaluated on day 42. The results showed that the mean serum GnRH, LH and testosterone levels, and the CESR of all the treated groups were significantly (P < 0.05) lower than those of the untreated control on days 14, 28 and 42 of MSG administration. The mean serum TC levels of all the treated groups were also significantly (P < 0.05) lower than those of the control group on days 14 and 28. No lesions were observed on sections of the testes. It was concluded that MSG administration for 14, 28 and 42 days led to significantly lower serum levels of GnRH, LH, testosterone and TC, and significantly lower CESR.

The effect upon response latencies of random increases or decreases in stimulus intensity following a barrier-crossing response in a Mowrer-Miller shuttle box was studied. Stimulus change was contingent upon the response. 32 albino rats were randomly assigned to a control group which received no stimulation and to three experimental groups: Group L (subjected to changes in light), Group N (subjected to changes in noise), and Group LN (subjected to changes in light and noise). It was found that (a) in terms of mean latencies Group LN differed significantly from Group L and the control group. (b) Although the trial effect was significant, response latency did not consistently decrease over trials. (c) The mean number of spontaneous crossings was significantly larger for Group LN than for all other groups. (d) The mean number of spontaneous crossings increased over trials.
