Regardless of a patient's diagnosis, the care of his skin has been a primary concern of nurses throughout the years. Nurses has washed, dried, and rubbed the skin and have changed his position so as to keep the patient's skin in good condition and to protect him from pressure sores. However, we still find many-patients suffering from the pressure sores which may take many mothers or years of treatment and cost a lot to be repaired. In view of expensive cost for treatment of the sores and low ratios of nursing staff per patient for intensive nursing care, prophylaxis of the bed sores with sufficient aids is extremely important both for patients and for nurses. Therefore, the unique purpose of this study was to determine whether sponge is good enough to treat and prevent the pressure sore as compared with gel pad and sheepskin. Sixty patients in the age range of 15 through 45 who were in unconscious status or have difficulty of mobility were chosen between January and March of 1974 at Seoul National University Hospital. They were randomly assigned to each treatment and observed on every 4th day with regard to level of consciousness, status of mobility, moisture or dryness of the bed, general skin condition, intake of nutrition, vital signs and intervals of position change in comparison with the changes of skin over the bony prominences. The study results were reviewed in a statistical method analysis of valiance-to obtain the following findings: 1. There was no significantly different changes of skin over the sanctum or the trochanter in each group using get pad, sheepskin or sponge. It means that we may substitute sponge for expensive gel pad or sheepskin. 2. There was no significant difference among mean changes of patient's skin in relation to sheepskin, gel pad and sponge. 3. There was no significant changes of patient's akin in relation to level of consciousness, status of mobility, intake of nutrition, general skin condition, temperature, blood pressure or interval of position change. 4. There were no meaningful interactions between each treatment and level of consciousness, moisture or dryness of the bed, intake of nutrition, general skin condition, temperature or blood pressure. 5. Sheepskin and gel pad had significantly better influence on patients with limited mobility than on patients with immobility, and sponge on patients with immobility on than patients with limited mobility, 6. Sheepskin and sponge had meaningfully totter influence on patients changing position at below 2-hour interval, gel pad at 2-4-hour interval, sheepskin at 4-6-hour interval, and three of them at above 6-hour interval.

In July, three trials were conducted to evaluate the best sponge type and optimum PMSG dose to be administered to sheep under the Jordanian Badia (arid) conditions. In trial 1, three flocks (n=77, n=18 and n=47 for flocks 1, 2 and 3, respectively) were administered with 40 mg fluorogestone acetate (FGA) intravaginal sponges for 12 days before receiving 600 IU of PMSG at the time of sponge removal. In trial 2, 95 ewes were assigned to 4 groups to receive 300 (n=25), 450 (n=27), 600 (n=22) or 750 (n=21) IU of PMSG following a 12 d FGA 40 mg sponge insertion period. In trial 3, 60 ewes were assigned to 3 groups (n=20) to receive either FGA 30 mg, FGA 40 mg or medroxyprogesterone acetate (MAP) 60 mg intravaginal sponges all followed by an administration of 600 IU of PMSG at sponge removal. In all trials, rams were isolated 1 day before sponge insertion and were allowed back with the ewes at sponge removal. Estrual responses and lambing data were collected. The effects of treatment, milking status and face color on estrual responses and lambing data were examined. In trial 1, greater first cycle conception rate (p<0.05), twinning rate (p<0.01) and the number of lambs born/served ewe (p<0.01) were observed in flock 2 compared with flocks 1 and 3. Neither face color nor milking status had any influence on the measured parameters (p>0.05). Despite low lambing rate in trial 2, ewes receiving 600 IU of PMSG had greater (p<0.05) number of lambs born/served ewe compared with ewes receiving 450 IU of PMSG. Regardless of PMSG dose, intervals to detected estrus occurred 10 h earlier (p<0.01) in dry than lactating ewes. Similar to trial 2, lambing rate was depressed in trial 3. The expression of estrus was advanced (p<0.05) in ewes receiving MAP 60 mg sponges compared with those receiving FGA 30 and FGA 40 mg sponges (42$\pm$3.1, 49$\pm$3.1 and 49$\pm$3.1 h post sponge removal in ewes receiving MAP 60 mg, FGA 30 mg and FGA 40 mg sponges, respectively). Other parameters were not influenced (p>0.05) by sponge type, milking status and face color. Data show that a 600 IU dose of PMSG tends to give the best lambing results. In addition, results indicate that the use 60 mg MAP sponges for estrus synchronization may be more appropriate under the Jordanian Badia conditions during late seasonal anestrus.

It is recognized that Schwann cells (SC) are essential for peripheral nerve development and regeneration. SIS (small intestinal submucosa) consists of some growth factors which can stimulate cell activity without immune rejection responges. SCs were harvested from the femurs and tibias of female Fischer rat and then suspended with $2{\times}10^6$ cell/sponge in SIS sponge. Fischer rat received an implant consisting of the SCs and the SIS sponge at the place of a 5 mm gap created by the sciatic nerve resection. Thin sections were stained with H &E staining and immunostaining of S-100, GFAP and NF after 1, 2, and 4 weeks. It was observed that the effects of the SIS sponge with SCs on neuroinduction(Group II, with scaffold & cell) are strong as much as uninjured model(Control I), and significantly stronger than SIS sponge model (Group 1, with scaffold only) and blank model (Control II). In conclusion, these results suggest that SIS sponge filled with SCs may have an important role for peripheral nerve regeneration of tissue engineering.

The replacement of wheat flour with 4 to 24% soy fiber FIBRIM(R)1450 was evaluated to determine its effect on the properties of sponge cake. The volume and specific loaf volume decreased as the amount of soy fiber increased. In addition, the protein content and water holding capacity (WHC) were negatively correlated with the specific gravity of batter and the specific loaf volume of sponge cake, whereas there was no correlation between the mixograph characteristics and specific loaf volume of sponge cake in response to the addition of soy fiber. Furthermore, the symmetry and uniformity indices were not influenced by the addition of soy fiber. However, the L values of sponge cake crust and crumb decreased with increasing amounts of soy fiber, whereas a and b values were not affected. Additionally, the hardness, gumminess, and chewiness of the sponge cake all showed positive correlations with the protein content, sedimentation value, WHC and alkaline water retention capacity. Finally, the results of sensory evaluation indicated that external and internal colors, grain, texture, and flavor were not influenced by the addition of soy fiber, but that supplementation with over 20% soy fiber resulted in a slight decrease in taste and overall acceptability.
