Abstract
Vanadyl sulfate trihydrate was given by gavage to streptozotocin-induced diabetic rats for 21 days at doses of 0, 25, 50, or 75 mg/kg/day. In marked contrast to the reduction in plasma glucose observed in diabetic animals given vanadyl sulfate via drinking water, diabetic rats given vanadyl by gavage were not characterized by normoglycemia. Similarly, in contrast to the normalizing effect of vanadyl in drinking water, vanadyl by gavage had only a minimal influence on diabetes associated hyperphagia and polydipsia. Despite the lack of marked effect of vanadyl by gavage on the above parameters, tissue vanadium accumulation in the gavaged rats was similar to that reported for rats given vanadium by drinking water. The present results (taken together with previous data) show that the administration of vanadium by gavage is not a viable alternative to the use of insulin in diabetes treatment.

Abstract
Although it has been reported that vanadate is effective in diminishing the expression of diabetes in the rat, the severe toxic side effects noted in the vanadate-treated animals suggest that chronic oral administration of vanadate argues against its use in human diabetes. The present study was conducted to evaluate the effects of the chelator Tiron on the mobilization of vanadium after administration of sodium metavanadate in the drinking water (0.20 mg/ml) of streptozotocin-induced diabetic rats for 35 days. Intraperitoneal treatment with Tiron (300 or 600 mg/kg) was initiated after three weeks of vanadate administration and continued for two weeks. The ameliorative effects of vanadium with respect to diabetes were not diminished by the administration of Tiron, but the accumulation of vanadium in kidney and bone was significantly decreased in the Tiron-treated groups and diabetes associated increases in serum GOT, GPT and cholesterol were diminished with Tiron treatment. It is concluded that the coadministration of metavanadate and Tiron may be of potential value for treatment of diabetes mellitus.

Abstract
The effect of repeated intraperitoneal administration of Tiron (4,5-dihydroxy-1,3-benzenedisulfonic acid), ascorbic acid, deferoxamine (DFOA) or 2-mercaptosuccinic acid on urinary excretion and tissue distribution of vanadium was assessed in rats which had previously received 12 intraperitoneal injections of sodium metavanadate (1.84 mg/kg per injection) or vanadyl sulphate trihydrate (6.35 mg/kg per injection) during a 4-week period. Chelating agents were administered daily for 5 days at doses equal to one-eighth of their respective LDSO. Only Tiron significantly decreased the tissue concentration of vanadium, whereas DFOA and Tiron significantly enhanced the urinary excretion of vanadium after repeated parenteral administration of sodium metavanadate. Again, only Tiron significantly increased the urinary elimination of vanadium following vanadyl sulphate administration. The results of this study show that Tiron has potential beneficial effects in the treatment of repeated intraperitoneal vanadium poisoning, while the effectiveness of DFOA is very uncertain. 2-Mercaptosuccinic and ascorbic acids were not effective as antidotes for parenteral vanadium intoxication.

Abstract
To evaluate the influence of citrate on the potential developmental toxicity of high doses of aluminum (133 mg/kg/day), three groups of pregnant Sprague-Dawley rats were given by gavage aluminum hydroxide (384 mg/kg/day), aluminum citrate (1064 mg/kg/day), or aluminum hydroxide (384 mg/kg/day) concurrent with citric acid (62 mg/kg/day) on gestational days 6 through 15. Control animals received distilled water. At termination on gestation day 20, live fetuses were examined for external, visceral, and skeletal alterations. There were no significant differences between controls and Al-treated rats on pre- or postimplantation loss, number of live fetuses per litter, or sex ratio. Fetal body weight was significantly reduced in the group treated with Al(OH)3 and citric acid. Although no increases in the incidence of malformations were observed, the incidence of skeletal variations was significantly increased in the group given Al(OH)3 concurrent with citric acid. In summary, although the administration of citric acid did not modify the lack of embryotoxicity and teratogenicity of Al(OH)3 in rats, some signs of maternal toxicity and fetotoxicity could be observed in this group.

Abstract
Eight groups of female Sprague-Dawley rats were treated with 281 mg Al(OH)3/kg/day by gastric intubation five times a week for five weeks. Concurrently, animals in seven groups received ascorbic acid (56.3 mg/kg/day), citric acid (62 mg/kg/day), gluconic acid (62.7 mg/kg/day), lactic acid (28.8 mg/kg/day), malic acid (42.9 mg/kg/day), oxalic acid (28.8 mg/kg/day), and tartaric acid (48 mg/kg/day) in the drinking water. The eighth group did not receive any dietary constituent in the water and was designated as the control group. Animals were placed in plastic metabolic cages and urine was collected during the treatment period. The liver, spleen, kidney, brain and bone aluminum levels of each rat were measured, as well as the total amount of aluminum excreted into urine. All the dietary constituents significantly increased the aluminum concentrations in most of the tissues, with ascorbic and citric acids showing the highest rate of aluminum accumulation. In contrast, no significant differences between control and treated rats were observed in the concentrations of aluminum excreted into urine. In view of these results, we suggest that the effects of the simultaneous ingestion of aluminum hydroxide and those dietary constituents in uremic animals should be evaluated. Meanwhile, the diet of uremic patients should be carefully monitored.

Abstract
In the present investigation, the effects of oral administration of sodium metavanadate, sodium orthovanadate and vanadyl sulphate to alleviate some signs of diabetes in streptozotocin-treated rats have been evaluated. Streptozotocin-induced diabetic rats drank aqueous solutions (NaCl, 80 mM) containing sodium metavanadate (0.15 mg/ml), sodium orthovanadate (0.23 mg/ml), or vanadyl sulphate pentahydrate (0.31 mg/ml) for 28 days. The vanadium-treated animals were compared to controls, either diabetic or nondiabetic, receiving drinking water containing NaCl (80 mM) only. Daily food and fluid intake were significantly decreased in the vanadium-treated animals relative to diabetic controls. Also, vanadium treatment reduced the level of hyperglycemia in diabetic rats, with sodium metavanadate being the most effective of the vanadium compounds tested. However, daily vanadium intake was significantly lower in the animals receiving sodium metavanadate. Signs of toxicity were observed in all vanadium-treated animals as evidenced by some deaths, decreased weight gain, and increased serum concentrations of urea and creatinine. Moreover, vanadium was detected in all tissues analyzed. Although some signs of diabetes were improved by vanadium treatment, because of the severe toxic side effects noted in all of the vanadium-treated animals, it seems evident that oral vanadium administration is not a suitable therapy of diabetes mellitus in streptozotocin-diabetic rats.

Abstract
A case-control study of 271 testicular cancer cases aged 18-42, including 60 seminomas and 206 other germinal cell tumours, and 259 controls was carried out to study the association between occupation and testicular cancer risk. Study subjects were identified at three medical centres, two of which treat military personnel. Controls were men diagnosed with a cancer other than of the genital tract. Associations were identified between professional employment (administrators, teachers and other professionals) and risk for testicular seminoma, OR = 2.8 (95% Cl: 1.4-5.4) and between employment in production work and risk for other germinal cell tumours, OR = 1.8 (95% Cl: 1.1-2.7). No specific occupations within these broad groups were responsible for observed increases. Self-reported exposure to microwave and other radio waves was associated with an excess risk for both seminomas and other germinal cell tumours. However, an assessment of radio wave exposure based on job title did not support this finding. Although testicular cancer has been increasing in recent decades among young males, occupational factors did not appear to account for a substantial proportion of testicular cancer occurrence in the population studied.

Abstract
The potential of aluminum hydroxide [Al (OH)3] to induce developmental toxicity in rats was evaluated in the present study. Al (OH)3 was given by gavage at dose levels of 192, 384, and 768 mg/kg/day to groups of pregnant rats from day 6 through day 15 of gestation. Control animals received distilled water. Pregnant rats were evaluated for body weight, weight gain, food consumption, appearance, behavior and reproduction data. Cesarean sections were performed on gestation day 20, and the fetuses were removed for teratological evaluation. No significant maternal or developmental toxicity was observed at any Al (OH)3 dose level. Consequently, the no-observed-effect level (NOEL) for Al(OH)3 maternal or developmental toxicity would be greater than or equal to 768 mg/kg/day, which was the highest dose tested. This dose would be equivalent to a 60 kg person ingesting 16 g Al/day.

Abstract
A procedure utilizing transvaginal aspiration of stimulated gametes followed by transcervical, ultrasound-guided catheterization of the tubal ostia was performed as a modification of the standardized gamete intrafallopian transfer (GIFT) technique. Among 14 patients with 16 cycles there were four normal, intrauterine pregnancies and one ectopic pregnancy. In two patients the beta-human gonadotropin level rose significantly and then started to fall; the patients aborted spontaneously. The procedure can be performed with a higher degree of patient acceptance than can traditional GIFT, and the success rate in this small series was promising.

Abstract
Eighteen chelating or reducing agents were tested to determine their relative efficacy as antagonists in acute intramuscular vanadyl sulphate intoxication in mice. The chelating or reducing agents were administered intraperitoneally to male Swiss mice at doses equal to one-fourth of their respective LD50. Therapeutic effectiveness (TEF) was calculated. In a subsequent experiment, the effect of EDTA, glutathione, DFOA, ascorbic acid, succinic acid, monosodium phosphate, Tiron, DTPA, and 2-mercaptosuccinic acid on the excretion, and distribution of vanadium was determined. Of the compounds examined, Tiron followed by ascorbic acid, and 2-mercaptosuccinic acid were effective in increasing the urinary excretion of vanadium. Tiron, and 2-mercaptosuccinic acid were also effective in reducing the concentration of vanadium found in kidney, the main target organ of vanadium accumulation. Tiron appears to be the most effective agent of those tested in the prevention of acute vanadium (IV) intoxication in mice.

Abstract
A multicenter, randomized, investigator-blind controlled trial was conducted to compare the safety and efficacy of a single, whole-body application of 5% permethrin cream with that of 1% lindane lotion for the treatment of scabies in 467 patients. At 14 +/- 3 days after treatment, the mean active lesion count decreased from pretreatment levels of 85 (range, 4 to 600) in both treatment groups to 14 (range, 0 to 133) in the permethrin group and to 15 lesions (range, 0 to 500) in the lindane group. At 28 +/- 7 days after treatment, complete resolution had occurred in 181 (91%) of 199 patients treated with permethrin and in 176 (86%) of 205 patients given lindane. Pruritus due to scabies persisted at 28 +/- 7 days in 14% of the permethrin group and in 25% of the lindane group. The most frequent adverse effects were new or increased pruritus and mild, transient burning or stinging; the latter was slightly more frequent following permethrin treatment and appeared to be related to severity of infestation. Because of a lower potential for neurologic toxicity, permethrin may be preferable to lindane for the treatment of scabies particularly in children.

Abstract
We studied, by means of quantitative histopathological methods, the changes that took place in B16 melanoma implanted into C57BL/6J mice after combination treatment of hyperthermia, melphalan, and 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU). The studies were made on animals sacrificed on days 11, 18, and 25 after implantation. Tumors in treated animals showed a progressive delay in growth, a noticeably reduced number of metastases, and diminution of proliferative capacity. However, this treatment did not affect necrosis, stroma, capsule, or cell infiltration. Ultrastructurally, signs of cell damage were constantly present.

Abstract
The aim of this paper has been to check the diagnostic ability of Scanning Electron Microscopy (S.E.M.) to determine wound direction. We have studied incised wound margins caused by steel blades in human skin samples from cadavers by S.E.M. It was found that a lateral accessory tail existed in 65% of the entrance edges. This finding was recorded in all the cases when wound direction was perpendicular to Lancer's lines of the skin area in which the wound was located. No similar finding in the exit tails was noticed. The depth and length of the wound margins was less accurate an index of the wound direction than a lateral accessory tail. We think that this finding could be useful in determining the entrance margin in incised wounds.

Abstract
In this paper we describe a new beta-lactam-binding protein from the cell envelope of Escherichia coli. It can be detected in cells grown at either 37 or 42 degrees C in medium containing glucose but not in cells grown at 30 degrees C. This novel component has an apparent molecular size that is 2.0 kilodaltons larger than that of penicillin-binding protein 3 and is derived from the latter through a divalent-cation-mediated process probably catalyzed by components located in the periplasmic space. The significance of this protein with regard to regulation of the amount of functional penicillin-binding protein 3 in the cell is discussed.

Abstract
A new technique for vaginal intratubal insemination (VITI) and transvaginal gamete intra-Fallopian transfer (TV-GIFT) using endosonography has been developed. A total of 47 infertile couples were treated using a K-JITS 1000-1100 catheter (William Cook, Australia; Jansen Anderson Intratubal Transfer Set) introduced by Jansen and Anderson in Sydney, Australia, and endosonographic control with a Kretz Combison 310 echograph and a 5/7.5 MHz vaginal sectorial transducer. In 40 couples, the VITI technique was used, and in the other seven couples, TV-GIFT was used. Fifteen pregnancies (37.5%) were obtained in 63 VITI cycles (23.8% per treatment cycle) and three with TV-GIFT (42% per treatment cycle). A review is also presented of the migration--sedimentation technique used for management of male factor in an artificial insemination programme.

Abstract
Two orthotopic liver transplant recipients underwent percutaneous transluminal angioplasty (PTA) for stricture of the hepatic arterial anastomosis. In both, arterial revascularization was effected by end-to-end anastomosis between the donor common hepatic artery and the recipient's hepatic artery. Both patients had elevated liver enzyme levels, abnormal results on duplex Doppler images, and severe stricture on angiograms. In one patient, percutaneous biopsy revealed graft ischemia. PTA was performed successfully without complications. PTA produced substantial improvement in biochemical, duplex Doppler, histologic, and angiographic patterns. Both patients were asymptomatic 5 and 6 months after PTA.

Abstract
The functional results of different types of plasty were evaluated in 46 patients who had undergone esophageal replacement for different pathologies. The patients were classified into three groups according to the type of plasty: I) 19 ileocecocolonoplasties (ICC), II) 11 left colonoplasties (LC), III) 16 gastroplasties (GP). The postoperative studies made were: a) clinical evaluation, b) radiological barium contrast study, c) isotopic transit of semisolid food marked with 99m-Tc colloidal sulfur and d) manometry. The clinical evaluation disclosed no significant differences between the three groups. Isotopic scans revealed more rapid emptying of the ICC, with elimination by the ileal segment in the first minute of 76.3 +/- 3.3% of the isotope, and by the entire plasty of 79.4 +/- 4.2% in 15 minutes (p less than 0.001). The manometric study showed non-response by the GP. The motor activity of the terminal ileoplasty was greater than that of the other plasties studied, and that of the right colonoplasty was greater than that of the left (p less than 0.01). Likewise, the clearance of acid (HCl 0.1N) by the ICC was more rapid than that of the LC (p less than 0.01). It is concluded that, functionally, the ICC is a better long esophagoplasty than the other procedures studied.
