The effect of Trypanosomiasis on concentrations of plasma steroids and semen characteristics was studied in 24 dromedary bulls. Based upon the parasitological and serological diagnosis, 18 bulls were found infected with Trypanosoma evansi (Group 2) and six were found to be free from infection and served as controls (Group 1). The infected animals exhibited signs of anaemia indicated by the decrease of packed cell volume (PCV) and haemoglobin concentration (Hb), pale mucus membranes, weight loss, lethargy, weakness and dullness. However, five animals (27.8%) of the infected group revealed elevated rectal temperatures and three animals (16.7%) revealed testicular degeneration upon palpation of their scrotal contents. Concentrations of plasma oestradiol-17beta (86.5 +/- 8.6 pg/ml versus 232.5 +/- 74.4 pg/ml) and testosterone (4.8 +/- 0.7 ng/ml versus 2.7 +/- 1.5 ng/ml) were significantly different (P < 0.05) between the control and infected bulls. Evaluation of the semen collected by electroejaculation and evaluated by a computerized cell motion analyzer revealed normal semen characteristics in the control animals compared to deteriorated ones in the infected bulls. There were highly significant (P < 0.01) decreases in sperm count (12.2 +/- 1.3/ml versus 6.5 +/- 4.9 x 10(6)/ml), motility percentage (68.2 +/- 6.7% versus 27.4 +/-15.6%), percentage of live spermatozoa (73.2 +/- 8.3% versus 35.8 +/- 8.2%) and increases in percentage of morphological abnormalities (3.3 +/- 0.6% versus 15.9 +/- 1.0%) in the infected group. An examination of the plasma hormonal profiles and semen characteristics in the infected bulls indicated that altered Sertoli cell function due to formation of immune complexes in four bulls (Group 2A), pituitary dysfunction in six bulls (Group 2B), testicular degeneration in three bulls (Group 2C) and finally trypanotolerancy in five bulls (Group 2D) are possible factors responsible for poor semen characteristics and infertility induced by T. evansi infection in dromedary bulls.

With the growing incidence of infertility in the modern world, artificial fertilization techniques provide new hope for many would-be parents. However, side-effects of the treatment can have a huge impact on patients and their families. This article employs Roy's adaptation model to study a patient with ovarian hyperstimulation syndrome who had undergone artificial fertilization treatment. Under careful assessment and examination, the author discovered that the patient suffered from such problems as malnutrition, fluid overload, pain and lethargy, etc. By employing skillful communication techniques and the display of empathy, the author helped to alleviate the patient's sufferings during treatment, as well as providing professional knowledge and advice. To help the patient in resolving difficulties that might have been encountered in the family, the author also exercised the idea of the family as core. The author hopes to share the knowledge that, in the care of patients with infertility, it is vital that health care professionals look after their psychological requirements as well as their physical care, in order to provide optimum care.

Anesthetic agents were developed in the 1700s, and nitrous oxide was first used in 1884. Research on the effects of waste anesthetic gas exposure started appearing in the literature in 1967. Short-term exposure causes lethargy and fatigue, and long-term exposure may be linked to spontaneous abortion, congenital abnormalities, infertility, premature births, cancer, and renal and hepatic disease. Today, perioperative staff members are exposed to trace amounts of waste anesthetic gas, and although this exposure cannot be eliminated, it can be controlled. Health care facilities are required to develop, implement, measure, and control practices to reduce anesthetic gas exposure to the lowest practical level. Exposure levels must be measured every six months and maintained at less than 25 parts per million for nitrous oxide and 2 parts per million for halogenated agents to be compliant with Occupational Safety and Health Administration standards.

Sheehan's syndrome, first described in 1937, is characterised by postpartum haemorrhage, pituitary necrosis, lactational failure and hypopitutarism. Presentation is variable and late presentations are not unusual due to partial ischaemic injury of the pituitary and gradual loss of endocrine function. A history of postpartum haemorrhage is usual but in some cases it is not elicited. Presentations such as malaise, fatigue, hypoglycaemia, decline in cognition, hyponatraemia, pancytopoenia, osteoporosis, secondary infertility, confusion and coma have all been reported. Two interesting cases of Sheehan's syndrome are presented that were diagnosed in the eighth decade; one due to atypical presentation of recurrent hyponatraemia and confusion, another from hypoglycaemic coma and symptoms of malaise and lethargy.

This article demonstrates the medicinal usage of ginseng in the West from 1660 to 1914. Asian[Korea] ginseng was first introduced into England in the early 17th century, and North American ginseng was found in the early 18th century. Starting from the late 17th century doctors prescribed ginseng to cure many different kinds of ailments and disease such as: fatigue general lethargy, fever, torpidity, trembling in the joints, nervous disorder, laughing and crying hysteria, scurvy, spermatic vessel infection, jaundice, leprosy, dry gripes and constipation, strangury, yellow fever, dysentery, infertility and addictions of alcohol, opium and tobacco, etc. In the mid-18th century Materia Medica began to specify medicinal properties of ginseng and the patent medicines containing ginseng were widely circulated. However, starting in the late 18th century the medicinal properties of ginseng began to be disparaged and major pharmacopoeias removed ginseng from their contents. The reform of the pharmacopoeia, influenced by Linnaeus in botany and Lavoisier in chemistry, introduced nomenclature that emphasized identifying ingredients and active constituents. Western medicine at this period, however, failed to identify and to extract the active constituents of ginseng. Apart from the technical underdevelopment of the period, the medical discourses reveal that the so-called chemical experiment of ginseng were conducted with unqualified materials and without proper differentiation of various species of ginseng.
