    Notes: To estimate the risk and evaluate the long-term outcome of knee and ankle injuries in former national team elite football, 69 players were randomly selected, followed by clinical and stress radiographic examinations. Thirthy-nine players (49 knees) had had knee injuries and 29 ankle injuries (35 ankles). The median time from injury until study examination was 25 years. The knee injuries were tears of the medial collateral ligament (MCL) in 24 cases combined with rupture of the anterior cruciate ligament (ACL) and meniscus lesions in three. Meniscus lesions had occurred in 17 cases including three combined with ACL and MCL and another two with ACL ruptures. Isolated rupture of the ACL had occurred in four cases. The ankle lesions were in 26 of 35 cases ruptures of the lateral ligaments. In all, 12 players had completely stopped football and three had changed occupation. Signs of arthritis were present in 63% of the injured knees and in 33% of the injured ankles. The incidence of arthritis in the group of 17 uninjured players was 26% in the knee and 18% the ankle. In elite football players knee and ankle injuries seem to have a serious long-term outcome, but also uninjured players have a higher risk of developing arthritis than the normal population.

    Renal function in streptozotocin-diabetic rats (1981)

    Notes: Summary Renal function was examined with micropuncture methods in the insulin-treated streptozotocin-diabetic rat. Kidney glomerular filtration rate was significantly higher in the diabetic rats (1.21 ml/min) than in the control group (0.84 ml/min) Nephron glomerular filtration rate increased in proportion to the rise in kidney glomerular filtration rate (diabetic rats: 37.0 nl/min; control rats: 27.9 nl/min). Likewise renal plasma flow was significantly higher in the diabetic rats (4.1 ml/min) than in the control group (3.0 ml/min). Glomerular capillary pressure was identical in both groups (56.0 and 56.0 mmHg, respectively). The proximal intratubular pressure was significantly reduced in the diabetic rats (10.4 mmHg; control value: 12.5 mmHg). The effective glomerular ultrafiltration coefficient was slightly but not significantly higher in the diabetic rats (0.027 nl s-1mmHg-1) than in the control group (0.023 nl s-1mmHg-1). Kidney weight was significantly higher in the diabetic rats (1.15 g; control rats: 0.96 g) while body weight was similar in both groups (diabetic rats: 232 g; control rats: 238 g). Calculations indicate that the increases in transglomerular hydraulic pressure, renal plasma flow and ultrafiltration co-efficient of the glomerular membrane contribute about equally to the rise in glomerular filtration rate. The increases in the values of the determinants of glomerular filtration rate may be the result of renal hypertrophy. These studies suggest that this model provides a useful method for investigating kidney function in diabetes, which may have relevance for our understanding of the kidney abnormalities in human diabetes.

    Yolk protein in the pharaoh's ant: Influence of larvae and workers on vitellogenin and vitellin content in queens (1995)

    Notes: Summary Vitellin from the pharaoh's ant,Monomorium pharaonis (L.), was found to contain a single apoprotein with aM r of 198.3 kDa. The protein is a glycoprotein exposing mannose containing carbohydrate groups. Antibodies to pharaoh's ant vitellin (v t), raised in rabbits, were used to determine the head-, thorax-, and abdominal contents of vitellogenin and vitellin (v g+vt) in queens in relation to the presence or absence of larvae and workers using an ELISA test. Thev g+vt contents were also compared to the egg-laying rate and the weight of the queens. The results confirm the existence of a positive correlation betweenv g+vt contents in the queens and their access to larvae, probably related to the queens' preferential feeding on larval secretions. In queens without larvae the abdominalv g+vt contents declined in concordance with a low oviposition rate of 6–8 eggs/day. In spite of cessation of egg-laying within 24 hours after removal of both larvae and workers, the queens maintained basal contents ofv g+vt. This may indicate that the presence of larvae is not only essential for the nutrition of the queens, but also for the uptake of vitellogenin in the growing oocytes. This additional stimultive factor may be based on the queens' response to primer pheromones liberated by the larvae. v g+vt could not be demonstrated in workers or larvae with the ELISA test. If anyv g+vt is present in larvae and workers the amount is lower than the detection limit (1–2 ng/individual). This seems to rule out the possibility of transfer of proteins of this kind to the queens.

    Influence of larvae and workers on egg production of queens of the pharaoh's ant,Monomorium pharaonis (L.) (1995)

    Notes: Summary Social regulation of egg production and weight in queens was studied in relation to presence and absence of larvae and workers in the pharaoh's ant,Monomorium pharaonis (L.). Results were obtained by counting eggs and weighing queens under various conditions. The results confirm the existence of a positive feed-back loop between mated queens and their larvae as evident from a correlation (Y = 4.575 * X + 6.452) between the number of large worker larvae (X) and the egg yield (Y). This correlation seems to relate to the queens preferential feeding on larval secretions. Queens without larvae maintained a low level of egg production of about 6 eggs/day. Queens deprived of larvae as well as workers stopped producing eggs within 24 hours. Repletes, special workers, with greatly distended gasters functioned as a buffer retarding decline of egg production by feeding the queens during short periods without larvae.

    Notes: Summary Tamm–Horsfall glycoprotein, present only in the kidney thick ascending limb of Henle's loop, was studied here in streptozotocin diabetic rats. Tamm–Horsfall glycoprotein mRNA in situ hybridization was performed on snap-frozen left kidneys; the right kidneys were perfusion-fixed with 4 % paraformaldehyde and embedded either in paraffin, for Tamm–Horsfall glycoprotein immunohistochemistry, or in Epon for stereologic measurements. The length of the thick ascending limb of Henle's loop and the amount of glycogen were measured and the ultrastructure of the cells was evaluated. Urinary excretion of Tamm–Horsfall glycoprotein, calcium, magnesium and albumin was measured. After 10 and 50 days' duration of diabetes, kidney weight increased 20 and 41 %, respectively and the length of the thick ascending limb of Henle's loop increased 28 and 56 %, respectively, compared with controls. Substantial glycogen accumulations were present in the thick ascending limb of Henle's loop, and electron microscopy revealed a significant decrease in organelles and basolateral membranes. After 10 and 50 days' duration of diabetes, in situ hybridization of Tamm–Horsfall glycoprotein mRNA revealed a fourfold decrease, and the immunostaining for Tamm–Horsfall glycoprotein showed a threefold decrease as measured by densitometry. However, urinary Tamm–Horsfall glycoprotein excretion rate was increased fivefold and urinary concentration about twofold. Urinary calcium excretion increased threefold and magnesium twofold, but urinary albumin excretion was not significantly increased. The increased amount of Tamm–Horsfall glycoprotein, calcium and magnesium in the urine in diabetes occurs here concomitant with severe cellular damage in the thick ascending limb of Henle's loop.

    Notes: Summary A case of a new hereditary neurological condition with extensive calcifications of the central nervous system is described. The calcium deposits were especially localized to the leptomeninges, the first layer of the cerebral and cerebellar cortex, and along the ventricular wall. The neuropathological findings were in accordance with the clinic. The case was familial and the pedigree suggested an X-linked recessive inheritance.

    Nematode fauna in the sulphide-rich brine seep and adjacent bottoms of the East Flower Garden, NW Gulf of Mexico (1986)

    Notes: Abstract Nematodes sampled quantitatively in 1980 along a 96-m-long sulphide-rich brine seep gradient system in the NW Gulf of Mexico are characterized and compared with species from bottoms adjacent and beyond the influence of the brine. The age structure indicates permanent living populations within and outside the gradient system. Species composition shows a thiobiotic association and an oxybiotic association of nematodes, and each association is composed of two subgroups with a fifth group of species living in the ecotone. Such a distinction can also be shown in terms of dominance-diversity. The thiobiotic species are regarded as derived from their oxybiotic relatives and not the reverse. Nematodes describe environmental complexity since slenderness of the body correlates with the amount of dissolved sulphide in the environment. Body elongation, i.e. higher proportion of body surface area per unit body volume and shorter body radius, is suggested to be an adaptation to low oxygen tension in the environment as well as an adaptation to epidermal uptake of dissolved organic matter as additional nourishment of thiobiotic species. Analyses of buccal cavity structures and species distribution patterns show resource partitioning among most abundant species and congeneric species. Deposit feeders have a size diversity of buccal cavities similar to that of epistrate feeders and ominivore-predators. Deposit feeding prevails in the thiobios, but not in the oxybios.
