The concentrations of serum calcium, inorganic phosphorus, sodium and potassium from 24 cows with left displacement of abomasum and 21 cows with right displacement of abomasum on pre and postoperation were determined. 1. The preoperative levels of serum calcium in left and right displacement of abomasum were below normal and returned to normal levels postoperatively. 2. The preoperative levels of serum inorganic phosphorus in left and right displacement of abomasum showed slight increase preoperatively and consistent slight rise postoperatively. 3. The preoperative levels of serum sodium in left and right displacement of abomasum were slightly below normal and maintained low levels postoperatively. 4. The preoperative levels of serum patassium in left and right displacement of abomasum were low normal limit and increased to upper normal limit postoperatively.

Concentration of total protein, bilirubin, sodium and potassium in blood sera, and thymol turbidity of race horses, 78 males and 57 females aging from 2 to 5 years, were estimated. The results obtained were as follows: 1. Serum of race horses was low in protein concentrations as mean values of $5.48{\pm}0.77$ g/100ml. 2. Serum bilirubin was in normal range as mean values of total bilirubin, direct bilirubin and indirect bilirubin were $1.05{\pm}0.57$, $0.12{\pm}0.05$ and $0.93{\pm}0.58$ mg/100ml, respectively. 3. Mean value of serum thymol turbidity was $1.41{\pm}0.72$ S-H unit. 4. Mean values of serum sodium and potassium of race horses from Australia were $143{\pm}8.7$ and $3.85{\pm}0.53$ mEq/liter, respectively, and mean values of serum sodium and patassium of race horses from Japan were $142{\pm}9.4$ and $3.58{\pm}0.60$ mEq/liter, respectively.

The present study was carried out to investigate the relationship between the patients with toxemia of pregnancy and sodium, potassium and chlorine content in their blood serum and the intake diet. The author analyzed or titrated the concentration of serum and diet electrolytes for the antenatal and gynecologic inpatients (19 normal and 17 toxemic pregnant women ranged 23 to 32 years old) of the Han gang sacred Heart Hospital in Seoul and also determined their daily salt intake. The results obtained can be summarized as follows. 1. In the patients with toxemia of pregnancy mean sodium concentration in serum $(147.2{\pm}11.0mEq/L\;(338.5mg/dl)$ was greater than that of normal pregnant women (140 mEq/L corresponding to 322mg/dl) 2. In the toxemic pregnant women serum chlorine level (mean $113.4{\pm}5.6 mEq/L$ corresponding to 402.5mg/dl) showed the increase of 9.9 mEq /L(36.9 mg/dl) when compared to mean value of normal pregnant women(103.5mEq/L corresponding to 365.6mg/dl). 3. Mean potassium content in pregnant women with toxemia($4.59{\pm}0.7mEq/L$ corresponding to 17.9mg/dl) was similar to that of normal pregnant women(4.2mEq/L corresponding to 16.3mg/dl). 4. It was found that the salt content detected in the diet of toxemic pregnant women (mean $20.84{\pm}2.1g/day$) was greater than daily mean salt intake of normal pregnant women (19g).

This study investigated the effects of silver diamine fluoride (SDF) and potassium iodide (KI) treatments on the acid resistance of dentin exposed to secondary caries. Sixteen bovine dentin specimens with artificially induced caries were assigned to the following four groups: untreated negative control, untreated positive control, SDF-treated (SDF), and SDF and KI-treated (SDFKI). Multispecies cariogenic biofilms containing Streptococcus mutans, Lactobacillus casei, and Candida albicans were cultured on the specimens for 28 days, except for the negative control group. Specimens from the negative control group were stored in phosphate-buffered saline for that period. After a cariogenic biofilm challenge, the degree of demineralization was evaluated using micro-computed tomography (micro-CT). As a result of data analysis using micro-CT, the demineralization depths of the negative control, positive control, SDF, and SDFKI groups were 149.0 ± 7 ㎛, 392.0 ± 11 ㎛, 206.0 ± 20 ㎛, and 230.0 ± 31 ㎛, respectively. The degree of demineralization was significantly reduced in the SDF and SDFKI groups compared with that in the untreated positive control group. There were no significant differences between the SDF and SDFKI groups. This study confirmed that SDF and SDFKI treatments increase the acid resistance of dentin to secondary caries. KI did not significantly affect the caries-arresting effect of the SDF.

It was proved that cold tolerance of rice plants at the young microspore stage was affected by water temperature and nitrogen application from the spikelet differentiation stage to the young microspore stage, and this mechanism could be explained in the point of view of pollen developmental physiology. The cold tolerance of rice plants at the young microspore stage was severely affected by water temperature (Previous water temperature) and nitrogen application(Previous nitrogen application) from the spikelet differentiation stage to the spikelet differentiation stage. Although the duration is only 10 days or so from the spikelet differentiation stage to the young microspore stage, these days are very important period to confirm the cold tolerance of rice plants at the young microspore stage. The higher previous water temperature up to $25^{\circ}C$ and the deeper previous water depth up to 10cm caused the more cold tolerance of rice plants. Water irrigation of 10cm before the cretical stage showed lower cool injury than that of water irrigation of 20cm during the critical stage. The preventive effect of cool injury by combined treatment of the deep water irrigation before and during the critical stage was not additive but synergistic. The cold tolerance of rice plants grown in previous heavy nitrogen level was rapidly decreased when nitrogen content of leaf blade at the young microspore stage was excessive over the critical nitrogen level. Nitrogen content of leaf blade at the changing point of cold tolerance was estimated as about 3.5% for Japonica cultivars and about 2.5% for Indica x Japonica cultuvars. It is considered that these critical nitrogen contents of leaf blade can be used as a index of the safe critical nitrogen level for the preventive practices to cool injury. It was summarized that increase of engorged pollens per anther by high previous water temperature resulted from the increase of number of differentiated microspores per anther, otherwise, the increase of engorged pollens by the decrease of previous nitrogen level was caused by the decrease of the number of aborted microspores per anther.
