Effect of biotherapy T. cruzi 7x in several therapeutic schemes on experimental infection by Trypanosoma cruzi

Background: Biotherapy is used against infectious diseases treatment and prophylaxis and has been investigated by many researchers [1,2]. Aim: Assess the effect of biotherapy 7x T. cruzi on several treatment schemes, upon experimental infection by T. cruzi. Methodology: A blind, controlled and randomized by drawing experiment was performed. Male Swiss mice, four weeks old were utilized. Groups evaluated: IC – Infection Control (treated with water – 9 animals); TBBA7x3days – Treated with biotherapy 7x 3 days before and 3 days after infection (5 animals); TBB7x3days – Treated with 7x biotherapy 3 days before infection (5 animals); TBBAI7x3days – Treated with 7x biotherapy 3 days before infection and after infection indefinitely (6 animals). Animals were inoculated intraperitoneally with 1400 blood trypomastigotes Y strain. Biotherapy: prepared according to Farmacopéia Homeopática Brasileira [3]. Treatment plan: offered ad libitum, in the water (10µL/mL). Parasitological parameters: parasitemia was assessed according Brener’s technique. [4]. Clinical parameters: body hair aspect, edema, movement, diarrhea, body weight, temperature, food and water intake. Ethics: Registration 030/2008 UEM Ethics Committee for Experiments in Animals. Statistical analysis: was performed using the tests Kruskal Wallis and Mann-Whitney testes, significance 5%. Results: The best effect obtained was with the TBBA7x3days, both for clinical and parasitological parameters. It was expressed by lower parasitemia curve (p=0.04) and decrease of patent period tendency, of total parasitemia, of mortality and survival of the animals increase (Table 1). Evolution of parasitemia was distinct for the several treatment schemes. Survival of at least one mouse by treated groups is an extremely important data, since Y strain causes 100% mortality in Swiss mice. TBBAI7x3days group showed begger tendency in raising total parasitemia compared with IC. Although it might have occurred, this group presented 80% mortality rate compared with other groups. Animals from TBBA7x3days also showed better evolution of weight body, temperature, food (p=0.078-10%) and water intake, body hair aspect and edema development. Diarrhea and paralysis were only observed in IC group mice, highlighting the biotherapy use benefits. Conclusions: Best effect was obtained TBBA7x3days, both for clinical and parasitological parameters. It’s possible to speculate that in this regimen, biotherapy was able to modulate, more effectively, the host’s immune system, decreasing the number of parasites.

Evaluation of biotherapies T.cruzi 15x, 16x, 17x and "potency chords" in experimental infection by Trypanosoma cruzi.

Background: The biotherapies are drugs widely utilized against infectious diseases. Biotherapies’ profylatic and therapeutic action against Chagas Disease is currently being investigated, but it is needed to develop further controlled experiments “in vivo”, which could define more clearly: dilution, dose, time of use and, if possible, the action mechanisms of these ultradiluted medicaments [1,2]. Aim: Evaluate the effect biotherapies T. cruzi 15x, 16x, 17x and “potency chords”, on experimental infection by T. cruzi. Methodology: A blind, controlled and randomized by drawing test was performed. Animals: 29 male Swiss mice, four weeks old were utilized. The animals were kept at Parasitology Vivarium/State University of Maringá (UEM), in ideal conditions of temperature (22±2)ºC and photoperiod (light / dark cycle 12h). Mice have been inoculated intraperitoneally with 1400 blood trypomastigotes Y strain and divided in groups: IC – Infection control (treated with distilled water – 9 animals); TBBA15x3days – Treated with biotherapy 15x 3 days before and 3 days after infection (5 animals); TBBA16x3days – Treated with biotherapy 16x 3 days before and 3 days after infection (5 animals); TBBA17x3days – Treated with biotherapy 17x 3 days before and 3 days after infection (5 animals); TBBAChords3days – Treated with biotherapy 15x, 16x, 17x “potency chords”, 3 days before and 3 days after infection (5 animals). Biotherapies: prepared by a homeopathic pharmacist from UEM, according to Farmacopéia Homeopática Brasileira [3]. Biotherapies treatment schedule: diluted in distilled water (10µL/mL in ambar bottles – renewed each two days) offered ad libitum, 3 days before and 3 days after infection in all groups. Parasitological parameters: parasitemia was assessed from infection until death, according to Brener’s technique [4] with 5µL of blood collected from the tail vein and examined in optical microscope. Pre-patent period, patent period, total parasitemia, survival and morbidity were obtained from the parasitemia curve. Clinical parameters: Visually assessed (presence or absence): body hair aspect (bristling), edema, movement and diarrhea. Measured: body weight, temperature, food and water intake. Ethics: This study has been approved by the UEM Ethics Committee for Experiments in Animals - Registration 030/2008. Statistical analysis: was performed using the tests Kruskal Wallis and Mann-Whitney tests, significance of 5%. Results: There was not statistical difference between total parasitemia of the groups treated with biotherapies and the IC group (p=0.6819). The parasitemia curve of group TBBAChords3days was greater then the IC (p=0.0418). Despite this increase, patent period and mortality both showed a decreasing tendency, while pre patent period and survival time increased (p=0.373). The same tendency results were observed for TBBA17x3days results (Table 1). Survival of at least one mice in groups TBBA17x3days and TBBAChords3days is worthy of discussion, since Y strain causes 100% mortality in these experimental conditions. Groups TBBA17x3days and TBBAChords3days showed better evolution than IC group for body weight, temperature, food and water intake (p=0.05), body hair aspect and edema developing. Diarrhea and hind legs paralysis were only observed in mice belonging to groups IC and TBAA16x3days. Conclusions: Superior effect was obtained with biotherapies 17x and “Potency Chords”, both for clinical and parasitological parameters. “Potency chords” has proper effect which distinguishes it from the individual effects of the dilutions that compound it.

Using Nonscalp Hair in Scalp Hair Restoration—Theory and Execution

Harvesting of beard and body hair follicles for transplantation can be an effective form of treatment for appropriate patients. These patients may have had prior scalp transplantation and require repair but do not have sufficient scalp donor follicles remaining. Other patients will have these hairs mixed with scalp hairs to produce a greater density of hair on the bald scalp. Follicular unit excision (FUE) is preferred for body and beard follicle harvesting. Not all body hair is suitable for transplantation. Only hairs that are similar in appearance and behavior to scalp hair are suitable for transplantation to the scalp. The best nonscalp sources are the beard and anterior torso. Hairs from other body sites may be used for transplantation to the eyebrows. The standard techniques of FUE harvesting and anesthesia must be modified from those used in scalp harvesting to be safe and effective. With proper patient selection and technique, a significant cosmetic benefit can be achieved from these procedures.

Prevalence of Some Common Human Traits: An Updated Survey Report From Rajshahi University Campus, Bangladesh

Prevalence of some common human traits viz., body weight, height and body mass index (BMI), pattern baldness, body hair, chin, colour blindness, cheek dimples, earlobes, length of index finger, lips, nose, polydactyly, tongue and widow’s peak, and ABO blood groups along with their Rh-D antigen, were recorded and analyzed from 500 male and 1000 female students of the Rajshahi University (RU) Campus. Results showed that body weights of the male students (66.42±8.92 kg) were significantly higher (t= 35.14; P<0.001) than those of the female students (51.64±6.97 kg). The differences in BMI between males (23.32±3.26) and females (20.85±2.63), as expected, were also highly significant (t= 15.79; P<0.001) and notably, some of the female students were underweight (BMI< 18.5). No female had baldness compared to 15.8% bald males. Sparse body hair was prevalent over the dense body hair in both genders. The females had much higher smooth chin (89.6%) than the males (58.0%) but the males had much higher cleft chin (42.0%) compared to the females (10.4%). No female was colourblind whereas 7.4% males were colourblind. Absence of dimples was recorded in 92.4% males and 85.7% females. Attached earlobes were higher than the free earlobes in both sexes. Compared to the length of the ring finger, shorter index finger was prevalent both in males (85.4%) and females (68.6%). Frequencies of the broad lips in males and females were 53.4% and 58.6%, respectively. Females dominated large and broad noses (76.1%) in comparison with their male counterparts (61.4%). Polydactyly was a rare trait in the Campus, where only 2.2% males and 0.2% females had extra digits in their hands or feet. Tongue rollers (53.8%) outnumbered the tongue folders in males, but tongue folders (54.4%) outnumbered the tongue rollers in females. Males with widow’s peak were higher (25.8%) than that in the females (19.0). Blood groups in the males and females were in the order: B (32.0) > O (29.8) > A (22.4) > AB (15.8) and O (34.8) > B (34.4) > A (21.9) > AB (8.9), respectively. As a whole, 85.4% males and 98.0% females were Rh-positive where the blood group phenotypes did not affect body weight, height and BMI of the subjects (r=0.012; P=0.63). The relevance of these findings to the physical, physiological, social and clinical well-being of the humans has been discussed. Bangladesh J. Zool. 49 (2): 215-228, 2021

Preliminary Results of Vitamin D3 Application Combined With Anisodamine In the Treatment of Alopecia Areata in Children

Alopecia areata is a form of inflammatory hair loss that has been known for a long time, but its cause is largely unexplored. It is characterized by the patient's hair falling out in a circular pattern, which is why this disease is also called circular hair loss. This occurs in 80% of cases in the head area but can also affect the beard in men and in exceptional cases the entire body hair.

Properties and parameters for effective laser hair removal: A review

Because some people seek consultations for the removal of unwanted body hair, a permanent, safe, and non-invasive method of hair removal is needed. Laser hair removal has been a popular cosmetic procedure. It is a monthly treatment that may take up to ten sessions for permanent results. However, its efficacy varies due to the patient’s biological skin hair traits, the adjustment of the optimal parameters of the laser, and the protocols. The purpose of this review is to discuss the properties and parameters employed for laser hair removal. Once parameters for laser hair removal have been optimized, this treatment offers an effective and permanent solution for unwanted body hair.

Effect of Preoperative Skin Preparation Methods on Sternotomy Surgical Site Infection Rates: A Quasi-Experimental Study

BACKGROUND: A surgical site infection (SSI) reduces patient quality of life, increases morbidity and mortality rates, and increases health care costs. Results of studies comparing the effects of preoperative skin preparations are contradictory. PURPOSE: This study aimed to determine the effect of different preoperative skin preparation methods on the rate of SSIs in patients undergoing sternotomy. METHODS: A quasi-experimental study was conducted among 96 male patients undergoing sternotomy. The control group (CG) (n = 34) received routine care consisting of shaving body hair with a razor blade followed by instructions to take a bath or shower. In the intervention groups, patients received education about SSI prevention and body hair was removed with an electric clipper, followed by bathing with daphne soap containing olive oil (IG-1) (n = 31) or 2% chlorhexidine solution (IG-2) (n = 31). Patient demographic, medical history, surgical, and wound assessment variables were obtained. Potential SSI signs and symptoms were assessed for up to 90 days following surgery. RESULTS: Patient demographic, medical history, and surgical variables did not differ among the 3 groups. Sternal SSI occurred in 10.4% of all study patients; 8.8% of the CG patients, 12.9% of the IG-1 patients, and 9.7% of the IG-2 patients developed an SSI (P > .05). CONCLUSION: There were no significant differences in the rate of sternotomy SSI among the 3 groups. Randomized controlled trials with large samples are needed to compare these methods to determine optimal and affordable preoperative skin preparation methods.
