In recent years, stronger interest has been focused on the development of field application of polymer impregnation for the purpose of improving the durability of various reinforced concrete structures. Field polymer impregnation system is applied as the surface treatment of old or new cast-in-place reinforced concrete structures. The conventional field polymer impregnation system generally consists of base concrete drying, impregnant penetration and polymerization processes. The authors have developed a new labor- and energy-saving system in which the impregnant is penetrated immediately after the drying of the base concrete, and then the polymerization is accomplished by the heat or thermal energy remaining in the dried concrete in a short time. The purpose of this investigation is to establish the practical procedures for such a rapid field polymer impregnation system. In the laboratory tests, base concrete slabs are dried under various conditions by use of an LPG (liquefied petroleum gas) torch burner and a far infrared heater, and penetrated with methyl methacrylate-based impregnant by ponding method, subsequently polymerized by the remaining thermal energy. The behavior of the impregnant under heating conditions and the effects of the impregnant formulations and working life, base concrete temperature and remaining thermal energy on polymer penetration depth are examined. As a result, it is concluded that the polymer penetration depth can be controlled by the working life of the impregnant and the drying temperature-time product of the base concrete regardless of the drying methods and conditions of the base concrete. The temperature-time product expresses the approximate level of the remaining thermal energy. The practical procedures for the rapid field polymer impregnation system is proposed on the basis of the laboratory test results. Typical processes in the proposed procedures are explained in field *** rapid system can provide a polymer penetrati

There are only a few reports about upper extremity fractures in patients with Parkinson’s disease (PD). This is a case report of a PD patient with severe tremors who had proximal humeral fracture. We performed surgery for the left side and conservative treatment for the right side. The patient was a 73-year-old woman who had been diagnosed with PD 10 years prior to presentation. Open reduction internal fixation was conducted for the left proximal humeral fracture. 7 months after the left shoulder fracture, she fell resulting in a right proximal humeral fracture for which she underwent conservative treatment. Although bone union was obtained bilaterally, anterior subluxation occurred in the operated side 9 months postoperative. Screw remove was performed because perforation of the screw was observed in the humeral head and was causing pain. Currently, restriction in range of motion and subluxation may be seen on the side that received conservative treatment, although pain is absent and patient satisfaction is high. On the operated side, there is a marked restriction in range of motion, subluxation, and pain. Our experience revealed that conservative treatment was effective for proximal humeral fractures and that optimal bone union might be obtained even in patients with suboptimal PD control.

Degenerative disc disease is the most common cause of low back pain. Intervertebral disc abnormalities are commonly evaluated by magnetic resonance imaging (MRI), and Pfirrmann’s system involves the use of T2-weighted images (T2WI) to classify disc degeneration. However, as this classification is based on visual evaluation, it is not possible to quantify degeneration using this method. The present study was performed to establish an MRI-based intervertebral disc classification system using diffusional kurtosis imaging (DKI), to quantify intervertebral disc water content according to the Pfirrmann classification. Sagittal mean diffusional kurtosis (MK) mapping was performed for the L3/4, L4/5, and L5/S1 intervertebral discs in 32 patients (15 female, 17 male;age range, 24 - 82 years;mean age, 57.7 years). The degree of disc degeneration was assessed in the midsagittal section on T2WI according to the Pfirrmann classification (grade I - V). The relationships between MK values, which are correlated with intervertebral disc composition changes, and grade of degeneration determined using the Pfirrmann classification were analyzed. The MK values tended to decrease with increasing grade of degeneration, and differed significantly between grades I and IV, but not between grade IV and V (P < 0.05, Mann-Whitney U test). DKI is an effective means of detecting the early stages of disc degeneration. Therefore, DKI may be a useful diagnostic tool for quantitative assessment of intervertebral disc degeneration.

＜正＞ RAMP2 and -3 enable CRLR to function as an adrenomedullin （AM） receptor （CRLR/RAMP2 or -3）. We examined the functions of the transmembrane （TM） domain and cytoplasmic C-terminal tails （C-tails） of RAMP2 and -3 by cotrans-fecting their various mutants and chimeras into HEK-293 cells stably expressing human CRLR. FACS analysis revealed that substituting a Thr-Val sequence in the RAMP3 TM with the corresponding region （Ile-Pro） from RAMP2 significantly enhances AM-induced intemalization of CRLR. suggesting the RAMP2 sequence participates in the positive regulation of CRLR intemalization. Deletion of the C-tail from RAMP2 disrupted CRLR transport from the endoplasmic reticulum to the cell surface, markedly reducing 125I AM binding and evoked cAMP accumulation. Deletion of the C-tail from RAMP3 markedly enhanced CRLR intemalization. though there was no change in agonist affinity. The highly conserved Ser-Lys sequence within RAMP C-tails is involved in the cellular trafficking of the two AM receptors, but deleting the C-tails from RAMPs had no effect on lysosomal sorting of CRLR. Thus, the respective C-tails of RAMP2 and -3 differentially affect CRLR surface delivery and intemalization.

BACKGROUND:Liver cirrhosis causes peculiar systemic hemodynamics,and accurate evaluation of systemic hemodynamic state is important for cirrhotic recipients who underwent living donor liver transplantation(LDLT). We investigated the clinical advantages of a novel non- invasive method for measuring systemic hemodynamic parameters using indocyanine green(ICG). METHODS:Twenty-eight LDLT recipients were evaluated. Simultaneous measurements of cardiac output(CO)using Swan-Ganz catheters and pulse dye densitometry(PDD) were performed every 12 hours after LDLT.A total of 155 sets of simultaneous CO measurements were obtained. RESULTS:The CO values obtained by PDD correlated well with those obtained by the invasive catheter *** addition,none of the recipients developed any side-effects, and we verified the safety of repeated ICG *** is safe,even for repeated use over time in the same recipient. Moreover,PDD can measure the blood volume(BV).CONCLUSIONS:Since the cirrhotic systemic hemody- namics characterized by high CO and large BV remains, even after LDLT,the ability to measure CO and BV in a non-invasive,simple and real-time manner using PDD has advantages for cirrhotic LDLT recipients.

Objective To study the effects of Cow＇s milk on the reproduction in male mice. Methods Twenty-four male mice were divided randomly into two groups： milk group （M） and control group （C）. Each mouse was given 10 mL milk per day from 4 to 16 weeks in the group M. At the age of 17 weeks, all the mice were sacrificed. Results Serum testosterone was decreased in the group M （P=0.037）. No significant difference was found in weight of testes, seminal vesicle or adrenal gland of mice between the groups C and M. However, the weight of seminal vesicle decreased when expressed in g/100 g body weight in the group M. Epididymal sperm concentration, motility, morphology, and sperm head number were not affected by milk. Conclusion Cow＇s milk has adverse effects on the reproductive system in ICR male mice. Further studies are needed to clarify the specific effects of milk on reproductive health.

就取食过程中惯用左手还是右手的问题,我们对安徽省黄山的一群短尾猴进行了研究。结果发现在调查的33只个体中,9只惯用右手取食,11只惯用左手取食,另外13只对左右手的使用没有偏好。而且短尾猴在左右手的偏好方面也没有性别或年龄的差异。以往的一些研究表明猕猴类动物习惯于用左手取食,但是研究群的短尾猴并没有表现出这种倾向。我们将短尾猴的研究结果与猕猴属其它种类进行了比较,并讨论了猕猴属在这一行为上的多样性。
