Four experiments were conducted to determine the feasibility of using fluoride to mitigate bone fragility (osteoporosis) that develops in cage-reared broilers. The treatments consisted of adding sodium fluoride to the drinking water at the levels of 100, 150, 200, and 200 p.p.m. of fluoride in the four experiments, respectively. Birds were transferred from starting batteries at four weeks of age into six coops. Birds in three coops served as controls; birds in the other three coops were provided the fluoridated water ad libitum from four to eight weeks of age. No significant differences were observed in the final body weights between treated and control birds in the four experiments. The percentage of bone ash was usually greater from the treated birds than from the controls. These differences were significant (P less than or equal to 0.01) in the 150 and 200 p.p.m. treatments. At all levels of fluoridation, the strengths of humeri were significantly (P less than or equal to 0.01) increased. However, at the lowest level of fluoridation, 100 p.p.m., the increase was significant only in the females. Tibia strength was significantly (P less than 0.01) increased only at the 200 p.p.m. level. The increase in bone strength from fluoridation may be sufficiently great enough to result in a decrease in the incidence of bone breakage during the processing of coop-reared boilers.

In order to establish a secondary drive based on thirst, 16 male albino rats were deprived of water for 23 hours per day for 14 days in square cages. At the end of each 23-hour period, the Ss were placed in triangular cages with free access to water for 1/2 hour followed by 1/2 hour in a circular cage with no water available. On day 15 the Ss were divided into two groups following satiation in the triangular cage. The control Ss were placed in the circular cages with water present for the first time, and experimental Ss were placed in the square cages with water present for the first time. During this 1/2-hour period the experimental Ss drank significantly more than the control Ss which indicated the presence of thirst fear in the experimental group.

The importance of various stress factors involved in boxing and transit of wild and laboratory mice on a 28 hour journey was studied. Transference from laboratory cage to transit box alone caused weight loss; under the best conditions the laboratory mice lost 5% of their initial weight and wild ones 8%. Deprivation of food resulted in absolute loss of weight; from this death ensued when 20% of initial weight was lost: the smaller wild mice died sooner than the larger laboratory ones. Water deprivation resulted in retarding recovery of weight lost; wild mice took longer to recover than laboratory ones. It also caused weight loss and, in conjunction with deprivation of food, poor condition and death. Transit itself affected percentage weight loss and wheat consumption; wild mice were affected differently from laboratory mice in both respects. Genotype is seen to be important not only in controlling initial weight and activity level, but also--and independently of weight--the total food requirement. In the light of these findings current literature giving guidance on shipment of small mammals is shown to be inadequate, and certain recommendations are given.

The influence of thirty-four adamantane, protoadamantane, and homoadamantane derivatives on the phase transition characteristics of the bilayer in dipalmitoyl lecithin liposomes has been determined by differential scanning calorimetry. Each of these compounds induces a broadening of the phase transition profile of the lipid bilayer that is dependent upon the concentration of the solute and its molecular structure. The concentration--response curves obtained for these solutes suggest that the cage compound derivatives modify the phase properties and under some conditions may induce a phase separation in the doped bilayer. The relative activity sequences obtained for the compounds examined cannot be accounted for by simple considerations of lipid/water partition coefficients, substitution constants based on free energy relationships, or the relative polarities or sizes of substituent groups. The observations are consistent with the hypothesis that the position and orientation of a solute within the bilayer are critical factors in determining its relative potency. The position of a solute within the bilayer is significantly controlled by the presence of polar substituents and by the relative geometric relationships of these groups. For a given substituent group, the shape and size of the hydrocarbon cage becomes increasingly important. It is apparent that seemingly minor modifications in the structure of a solute can significantly alter its influence on the phase transition behavior of a bilayer.

9-Anthramide has electronic absorption and fluorescence spectra that, in water, are similar to those of anthracene. This result is attributed to steric hindrance of the 9-carboxamido group with the peri-hydrogen atoms in the 1- and 8-positions of the anthracene ring. However, in aprotic solvents, although the absorption spectrum of 9-anthramide is anthracene-like, its fluorescence spectrum is red shifted and structureless. This finding is attributed to excited-state rotation of the 9-carboxamido group into coplanarity with the anthracene ring and indicates that, in water, the hydrogen-bonded solvent cage affects the steric inhibition of conjugation in excited 9-anthramide. These findings suggest that studies of structure and reactivity of drugs in nonaqueous or solid matrixes are probably of only limited value, since in the strongly interacting aqueous media the aqueous solvent cage plays a substantial role in determining molecular structure and reactivity.

The effects of the population density on growth and life span of 21 to 26 months in SD-JCL-rats were investigated. The mean life spans of males and females were 23 and 24 months, respectively. The population density had no definite influence on increase in body weight of females, whereas a most accelerated growth of males was seen with 2 rats per cage. The total amounts of food intake of each animal throughout its life were about 15 and 11 kg for males and females, respectively, and those of water intake were about twice the food. No correlation was observed between the population density and the weights of the liver, kidney, heart and femur, though mals reared at 5 animals per cage had lightest adrenals among all the animals.

Hibernation was induced in Columbian ground squirrels by placing them in refrigerated cages equipped with urine-collection pans. On arousal, urine and blood were collected from each animal, which was then allowed to reenter hibernation. After several days the animal was sacrificed and bladder urine and another blood sample were taken. In addition, four active non-hibernating ground squirrels were placed in a cage at room temperature with neither food or water. Urine was collected at 9 and 26 hours and blood was collected at 0 and 26 hours. Although only seven of ten hibernating squirrels had a higher blood-urea level when sacrificed than during the previous arousal, the other three had very high levels in the arousal period and probably further excreted urea before entering hibernation. When total body urea was calculated on a body weight basis, all except one animal showed a greater level of urea during hibernation than in the previous arousal. During their period of dehydration, the non-hibernating summer squirrels showed a marked decrease in blood urea. The osmotic concentration of the urine from these squirrels was due less to urea than that excreted during arousal by hibernating squirrels. Thus, it appears that urea accumulates in the blood during hibernation and is excreted in the urine during arousal.

A glass metabolic cage was designed for studies involving newborn rats and small animals up to about 15 g. The metabolic chamber is a jacketed tube, open on both ends and closed with 0-ring clamps. Water is circulated around the cage to maintain a constant and physiologic chamber temperature. Information about the metabolic pathway of nutrients and drugs can thus be studied, and the effects of drugs on metabolism of substrates to CO2 can also be assessed in the newborn animal.

In supine dogs with saline-filled lungs the vertical gradient of pleural surface pressure (VGPpl) was not significantly different from -1 cm H2O/cm and that of transpulmonary pressure (VGPtp) was not significantly different from zero. Hence the hydrostatic gradient of the liquid was entirely taken up by the chest wall, the ribs being rigid in the direction of gravity and the diaphragm facing an equal hydrostatic gradient on both sides. In head-up dogs VGPpl was -0.8 cm H2O/cm when the level of the liquid in the filling system was 19.5 cm below the lung top and -0.5 cm H2O/cm when this level corresponded to the top. The hydrostatic gradient of the liquid was not entirely taken up by the rib cage because of its uneven regional compliance and VGPtp was reversed with respect to that of the air-filled lung. With fluorocarbon (specific gravity 1.75) filled lungs in the supine posture VGPpl was about -1.28 cm H2O/cm and VGPtp was reversed. In the head-up posture VGPpl was about -1.2 cm H2O/cm and VGPtp was reversed.

For flock vaccination, B1-type LaSota Newcastle disease water vaccine was used in chicken under commercial cage layer conditions using two different methods, Swish Corporation pipes and cups, and stainless stell troughs, in an effort to determine their effectiveness. The concentration of virus in trough and cup samples collected at the beginning and the end of the lines were the same except in one instance where little or no virus was transported to the end of the trough. Satisfactory results were obtained when the test was repeated a year later. Serum HI titers determined before and after vaccination demonstrated adequate flock serum titers and indicated that both methods of application were reasonably effective. In laboratory trials, different water pipes (black, polyvinyl chloride pipe and Hart cups, green, polyvinyl chloride pipe and Swish cups, and old, rusty, galvanized pipe) normally used in cage operations were tested. Our findings indicated that dried skim milk powder (DSMP) was essential in stabilizing vaccine virus in the containers tested and that an adequate vaccine virus concentration was maintained in the three types of pipe tested when DSMP was used. Without DSMP the vaccine titers were adversely affected.
