EFFECT OF ABOMASAL INFUSION OF ALANINE AND ASPARTIC ACID ON GROWTH HORMONE SECRETION IN SHEEP
Tanizawa, K.,Ashida, K.,Hosoi, E.,Matsui, T.,Yano, H. Asian Australasian Association of Animal Productio 1994 Animal Bioscience Vol.7 No.4
Effects of animo acids infusion into the abomasum on plasma growth hormone (GH) concentration were investigated using three wethers of 54 kg of average body weight. Wethers were infused with either 3.25 mmol/kg BW/day of sodium chloride solution (control), 3 mmol/kg BW/day of alanine (Ala), or 3 mmol/kg BW/day of aspartic acid (Asp) continuously for five days through an abomasum cathether in a $3{\times}3$ Latin square desing. On the day of starting infusion (day 0) and day 4 blood samples were collected from a jugular vein every fifteen minutes for six hours after feeding, and their GH concentrations were measured. Blood samples were also collected immediately before starting infusion (day 0), and before feeding of day 1, day 2 and day 4, and their plasma free amino acid concentrations were measured. In the animals infused with Ala, plasma free Ala concentration was increased by Ala infusion and it continued for four days. Plasma GH concentration of these animals increased on day 0, but this phenomenon disappeared on day 4. In the animals infused with Asp, the increase in plasma Asp concentration was observed only on day 1. Plasma GH concentration of these animals was not affected by Asp infusion. These results suggest that continuous Ala infusion stimulates GH secretion for a short period, but the effect would not last long, and that continuous Asp infusion does not affect plasma GH concentration.

Understanding how outpatient physiotherapy impacts on specific motor symptoms in Parkinson's disease (PD) is important for multidisciplinary care, but these points have not been clarified. We investigated the impact of outpatient physiotherapy on individual motor symptoms in PD patients. Fifty-five PD patients participated in the prospective cohort study, which examined the changes in motor symptoms after 90 min of outpatient physiotherapy program (1×/week for 10 weeks) and at 3 months follow-up. Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) motor score and tremor, rigidity, bradykinesia, and axial scores were assessed and compared pre-intervention, post-intervention, and at follow-up. Significant level was set at 0.05. Their MDS-UPDRS motor score and axial score significantly decreased post-intervention and at the follow-up. In the analysis differentiating effects based on the severity of motor symptoms according to the MDS-UPDRS motor score, only the moderate-severe group showed significant decreases in their MDS-UPDRS motor score, bradykinesia, and axial scores post-intervention, as well as in their MDS-UPDRS motor score, rigidity, bradykinesia, and axial scores at the follow-up. These findings suggest the outpatient physiotherapy might provide benefits, particularly in managing axial symptoms and bradykinesia, for community dwelling PD patients with moderate-severe motor symptoms within a multidisciplinary care framework.

We herein propose a new design procedure of a flexible container ship model where the vertical bending and torsional vibration modes are similar to its prototype. To achieve similarity in torsional vibration mode shapes, the height of the shear center of the model must be located below the bottom hull, similar to an actual container ship with large opening decks. Therefore, we designed a ship model by imparting appropriate stiffness to the hull, using urethane foam without a backbone. We built a container ship model according to this design strategy and validated its dynamic elastic properties using a decay test. We measured wave-induced structural vibrations and present the results of tank experiments in regular and freak waves.
