Birth of a healthy infant after bone marrow-derived cell therapy / 대한생식의학회지

Bone marrow-derived cell (BMDC) therapy has numerous applications as potential biological cells for use in regenerative medicine. Here, we present an original case of endometrial atrophy associated with genital tuberculosis in a woman who achieved a live birth with BMDC. This 27-year-old woman came to our center with endometrial atrophy and primary infertility. She had a past history of genital tuberculosis and amenorrhea. Her husband’s semen quality was normal. The patient was counseled for hysteroscopy due to thin endometrium and advised in vitro fertilization (IVF) with donor eggs in lieu of poor ovarian reserve. Several attempts of IVF with hormone replacement therapy (HRT) were made, but the desired thickness of the endometrium was not achieved. Uterine artery injection of BMDC through interventional radiology was given, followed by HRT for three months, which resulted in improved endometrium. This was subsequently followed by IVF with donor egg. The treatment resulted in the conception and delivery of a 3.1-kg baby boy through lower segment caesarean section with no antenatal, intranatal or postnatal complications. Recently, there has been massive interest in stem cells as a novel treatment method for regenerative medicine, and more specifically for the regeneration of human endometrium disorders like Asherman syndrome and thin endometrium, which was the reason behind using this strategy for treatment.

Técnicas de purificación y ruptura de quistes de Giardia spp / Purification and breaking techniques of cysts of Giardia spp

El objetivo de este trabajo fue optimizar y evaluar las técnicas de purificación, aislamiento y ruptura de quistes de Giardia spp a partir de heces formoladas para la obtención de ADN. La materia fecal filtrada fue sometida a 3 técnicas de purificación, utilizando soluciones de formol-éter, sacarosa y formol-éter más sacarosa. La solución de sacarosa permitió aislar los quistes con menos detritos. Los quistes purificados fueron tratados con 3 técnicas para la ruptura de los mismos: shock osmótico y calor, degradación química y shock térmico, acción enzimática y efecto mecánico. Solamente con la técnica de shock térmico, acción enzimática y efecto mecánico se observaron bandas fluorescentes en geles de agarosa. Los resultados de este trabajo permiten contar con una metodología de rutina, simple, que podría ser usada en los pasos previos a la técnica de PCR para la genotipificación de este parásito.

The purpose of this study was to optimize and evaluate the purification techniques, isolation and breaking of cysts of Giardia spp from fecal samples to isolate DNA. Filtrated fecal samples were tested in 3 purification techniques: Telleman solution, sucrose and Telleman plus sucrose. The sucrose solution let us to isolate the cysts with less detritus. The cleaned cysts were splited in 3 techniques to test the breaking: osmotic shock and heat, chemistry degradation and thermic shock, enzymatic action and mechanic effect. Only the last method was successful and showed bands in agarose gel. The result of this study shows a routine and common method which could be used in the previous steps to the PCR technique for the genotypification of these parasites.

Oral health of children from rural excluded villages (Trancas and Calchaqui valleys. Tucumán, Argentina)

The general hypothesis of the study was to evaluate strategically important rural areas to confirm their characteristics of [quot ]excluded population[quot ] and identify the priorities to allocate human and financial resources of the international co-operation project. The aim of this study was to establish the degree of development of villages in the Trancas and Calchaqui valleys, and the oral health of children living in areas involved in an integral study on excluded villages in the northwest of Argentina. These villages are considered a priority in the UNIR Project; they are thus strategically important as a link with countries of the MERCOSUR. Data on living conditions were obtained through direct inquiries (Project UNIR, W. K. Kellogg Foundation/University of Tucumán) and from data supplied by the Ministry of Economy, by the Ministry of Culture and Education and by the SIEMPRO project of the Secretariat of Social Development of the Ministry of Health. The Human Development Index (HDI) was calculated as World Bank criteria (1995), The studies on dental conditions were carried out in all the children between 12 and 14 years old, that is a total of 58 in the Trancas Valley and 212 in the Calchaqui Valley. RESULTS: (1) The HDI was 0.731 for the province, 0.56 for the Trancas Valley and 0.51 for Calchaqui valley. (2) The results are above the values for the country in the first case, and below the average country values for the valleys. (3) The percentage of BNN families reached 92

. The results for oral health show: (4) the DMFT were 6.34 +/- 0.07 in the Trancas Valley and 7.47 +/- 0.276 in the Calchaquí valley. (5) Carious teeth (CT) were the most important component of this index. (6) The absence of a specific and preventive assistance. CONCLUSIONS: (a) Children between 12 and 14 living in the Valleys of Trancas and Calchaqui (Tucumán, Argentina) are affected by severe levels of caries, with values above the national and province means. (b) The human development index is below that of the corresponding national and province levels. (c) Inhabitants of these valleys can be identified as socially and biologically highly vulnerable. (d) The indicators of cariogenic risk reveal the importance of introducing oral preventive care components to the health plan for the area focused on the excluded population.

Sex-related differences in the analgesic response to the rat tail immersion test

The analgesic response was evaluated by the tail immersion test in adult male (N = 30), female (N = 21) and androgenized female Wistar rats (N = 15). The reaction time for tail withdrawal from the hot water bath was faster for male than for female rats (3.48 +/- 0.12 vs 6.46 +/- 0.42 s). The reaction time of androgenized female rats was similar to that of male rats (3.08 +/- 0.16 s). Blockade of opiate receptors with naloxone (2 mg/kg, ip) decreased the sensitivity to the noxious stimuli in males (4.08 +/- 0.10 s) and in androgenized females (3.69 +/- 0.19 s) but increased it in female rats (5.01 +/- 0.41 s). These data show sex-related differences in the analgesic response evaluated by the tail immersion test and indicate that administration of androgens to newborn female rats affects their pain sensitivity.

Participation of opioid receptors in the modulation of the analgesic response by adrenal and gonadal glands

The invovlement of opiodi receptors in the analgesic response was evaluated by the tail-immersion test in simultaneously adrenalectomized and ovariectomized female Wistar rats (210-250g). The reaction time (mean ñ SEM) for tail withdrawal from hot water decreased significantly 2 weeks after surgery (3.52 ñ 0.20 s) when compared to intact animals (6.09 ñ 0.23 s). Hormonal replacement with dexamethasone (50*/day) did not affect reaction time (3.38 ñ 0.19 s). However, this response was restored by combined adrenal and gonadal steroid substitution (estradiol 5*g/day and progesterone 1.5*g 6h before the test) therapy (5.11 ñ 0.45 s) in animal treated with dexamethasone plus estradiol and 5.04 ñ 0.43 s in animals treated with dexamethasone plus estradiol plus progesterone). Naloxone (2mg/Kg decreased the reaction time of animals treated with adrenal and gonadal steroids (5.11 ñ 0.45 vs 4.15 ñ 0.44 and 5.04 ñ 0.43 vs 3.87 ñ 0.28 s, respectively, before and after naloxone) but failed to decrease it in rats treated with dexamethasone only (3.88 ñ 0.18 vs 4.34 ñ 0.25 s, before and after naloxone). These observations indicate that gonadal steroids are the most important steroid factors involved in the reaction time to tail immersion in hot water and confirm other reports that the opioid pathways modulating the neuronal circuitry require the presence of these hormones

The role of opioids in the analgesic response of rats during the estrous cycle

The analgesic response was evaluated by the tail immersion test in female rats during each phase of rhe estrous cycle. The reaction time (mean ñ SEM) for tail witdrawal from the hot water bath was faster during proestrus (5.78 ñ 0,28s) and decreased significantly during estrus (5.31 ñ 0.30s) and diestrus 1 (5.40 ñ 0.21s). Blockade of opiate receptors with naloxone (2mg/Kg, ip) invreased the sensitivity to the noxious stimulus only during proestrus (6.46 ñ 0.42 vs 5.02 ñ 0.41 s). These results suggest that the effects of gonadal steroids on nociception may involve an opioid pathway
