Abstract
We have developed a model of human sepsis in sheep. Twenty-four hours after continuous infusion of Escherichia coli endotoxin (lipopolysaccharide) (10 ng.kg-1.min-1) was begun, pulmonary transvascular fluid flux was almost five times the baseline values, cardiac output was nearly doubled, and mean arterial pressure was reduced by approximately 20 mmHg. At this time, the animals were killed and their lungs were fixed by endotracheal installation of 2.5% glutaraldehyde at 25 cmH2O pressure. Morphometry was performed by point counting, and data were expressed as relative volume density. Pulmonary edema and congestion were observed in sheep receiving lipopolysaccharide, whereas sham controls appeared normal. There was an increase in interstitial volume density. There was a significant increase (P < 0.01) in volume density of the pulmonary intravasculature (180%), interstitial macrophages (270%), and mast cells (240%). The volume densities of intravascular and interstitial polymorphonuclear neutrophils also showed a small insignificant increase.

Abstract
Inhalation of toxic materials has been shown injurious to the upper airways. Because secondary infection can slow the repair process, we undertook this study to determine the efficacy of antibiotic therapy in promoting the healing process of acute tracheal wounds. In 18 anesthetized sheep, a portion of the cervical trachea was exposed to smoke from smoldering cotton cooled to 38 degrees C. Nine received the broad-spectrum antibiotic, cefazolin, while none received saline placebo. At 13 days after injury, nonciliated and ciliated cell counts were 75% and 33% respectively of noninjured trachea receiving placebo, while in those receiving cefazolin, nonciliated and ciliated cell counts increased to 93% and 114% of paired noninjured trachea, respectively. We suggest that cefazolin therapy allows cell proliferation and differentiation to proceed more rapidly than observed with placebo therapy and thus may be a helpful augmentor to the healing of an acute airway injury.

Abstract
Toxic gases and fumes have been shown to be injurious to the upper airways. Repair of this injury involves proliferation and migration of surviving nonciliated cells, followed by differentiation to a normal phenotype. Because recent results suggested that growth factors could improve the outcome of an airway injury, we undertook this study to determine the efficacy of these materials as an initial treatment to accelerate the healing process. In 24 anesthetized sheep, a portion of the trachea was exposed to smoke from smouldering cotton cooled to 37 degrees C. Twelve received aerosolized epidermal growth factor plus platelet derived growth factor, while twelve received placebo. At 10 days after injury, nonciliated and ciliated cells were totally absent in the injured trachea receiving the placebo. In animals receiving growth factors, nonciliated and ciliated cells, however, were present (56% and 31% of uninjured trachea, respectively). At 13 days after injury, nonciliated and ciliated cell counts in those receiving placebo were 67% and 33% of uninjured, respectively. In sheep receiving growth factors, tracheal nonciliated and ciliated cell counts had increased to 105% and 64% of uninjured trachea, respectively. We conclude that growth factors therapy after airway injury stimulates cell proliferation and differentiation, and this therapeutic intervention to accelerate the repair process in acute airway injury is an approach applicable to humans.

Abstract
Noncardiogenic edema fluid often contains high levels of plasma proteins, which may inhibit the function of the lung surfactant complex and thus decrease interstitial hydrostatic pressures. We questioned whether, in the awake and standing animal, displacement of the alveolar surface lining would alter the permeability of the thin and sparsely supported pulmonary capillaries. Sheep prepared with lung lymph fistulae were given an aerosolized detergent (Det) to displace the lung surfactant complex. After the sheep were given Det, protein flux was significantly increased (P < 0.05). To validate the suggested permeability increase, pulmonary vein occluders were surgically implanted and experiments repeated with pulmonary arterial pressures elevated 10 mmHg above baseline. After 2 h of elevated pulmonary arterial pressure, lung lymph increased fivefold. At this time, lymph-to-plasma total protein concentration ratios for air and saline-plus-ethanol vehicle were significantly lower (P < 0.01) than baseline ratios (0.26 +/- 0.06 and 0.34 +/- 0.07, respectively). No significant difference could be shown in lymph-to-plasma ratios after the sheep were given Det. We conclude that disruption of the alveolar lining can cause a detectable increase in protein flux due, in part, to an increase in microvascular permeability.

Abstract
The cellular repair process of injured tracheal epithelium is described for sheep after exposure to toxic smoke containing high concentrations of acrolein. Fourteen fasted 3-4-year-old ewes had a portion of their cervical trachea exposed to cotton smoke for 20 min and then were sacrificed at various time intervals ranging from 1 to 22 days after exposure. Within 1 day of injury, columnar epithelium sloughed intact from the trachea with a concomitant reduction of nearly 35% in the basal cell population. At 2 days of recovery, the cellularity of the epithelium had increased and mitotic figures were observed in some tracheal epithelial and gland cells. By 8 days, undifferentiated hyperplastic cells increased to 30/100 microns, differentiated nonciliated columnar cells first appeared, and the basal cell population returned to a normal count of 13 cells/100 microns. Thirteen days after exposure, the undifferentiated hyperplastic cell population had declined to 7 cells/100 microns, nonciliated columnar cells were at control values, and some ciliated cells were identified. At 18 and 22 days, epithelium was normal in appearance and the count was 13 cells/100 microns. Data suggest that because the columnar epithelium sloughs intact with the cilia remaining active, toxic smoke may affect their attachment to the basal lamina. Furthermore, the regeneration process involves differentiation of hyperplastic cells in which they elongate down to the basal lamina, thus re-establishing the integrity of tall epithelium in the sheep trachea.

Abstract
Basal cells are differentiated with respect to junctional adhesion mechanisms and play a role in attachment of columnar epithelium to the basal lamina. Although much is known about nonciliated and ciliated cell differentiation during the repair process after injury, little is known about the basal cell. We studied the morphology of basal cells and quantitated junctional adhesion structures during repair of tracheal epithelium exposed to toxic cotton smoke. Ten adult ewes were given a smoke injury to a portion of the upper cervical trachea and were killed at 4, 6, 8, 10, and 18 days after injury for morphometric studies. At 4 days, there was a stratified reparative epithelium over the basal lamina, which was two to four cells in depth. The basal cells were identified by their hemidesmosome (HD) attachment to the basal lamina. Basal cells were about 69% larger than controls and flattened rather than columnar. The amount of HD attachment was 192% greater than controls. In contrast, volume density of cytokeratin filaments had decreased about 47%. Basal cells had returned to normal numbers and size and a columnar shape by day 18. The amount of desmosome (D) and HD attachment and volume density of cytokeratins had also reached control levels by day 18. These data indicate that morphology of basal cells changes during the initial stages of reparative regeneration but returns to normal by 18 days. Morphologic changes appear to reflect changes in size of the cell associated with cell division rather than differentiation of recently divided basal cells.

Abstract
A randomized double-blind study comparing the therapeutic efficacy of single dose of levo-praziquantel and mixed isomer praziquantel was carried out on 139 matched pairs of patients with schistosomiasis japonica. A single dose of either levo-praziquantel (20 mg/kg) or praziquantel (40 mg/kg) was given to each patient. Four and six months after treatment, the stool ova negative conversion rates were 94.85% and 96.27% for the levo-praziquantel group, and 97.06% and 94.03% for the praziquantel group, respectively; there was no statistically significant difference between the two treatments (P greater than 0.05). For lightly and moderately infected patients, a single 20 mg/kg dose of levo-praziquantel was as efficacious as 40 mg/kg of praziquantel. Moreover, levo-praziquantel produced fewer side effects than praziquantel. These results suggest that levo-praziquantel is the component of the mixed isomer preparation that is antihelminthic. Levo-praziquantel could be used therapeutically at half the current dose of the mixed isomer drug.

Abstract
Neutrophil chemotactic activity (NCA) and activity of myeloperoxidase (MPO) of the neutrophils in asthmatic patients during attacks and in remission and normal controls were determined. The results showed that NCA and activity of MPO in asthmatic patients during attacks were significantly higher than those in remission and in the controls. There was no difference of either NCA or the activity of MPO between asthmatic patients in remission and the controls. There was definite correlation between NCA and activity of MPO in asthmatic patients during attacks, but no correlation between the asthmatic patients in remission and the controls. The results suggest that chemotaxis and activation of neutrophils by neutrophil chemotactic factor may play an important role in pathophysiology of asthma.

Abstract
A smoke inhalation model was created in 22 adult male sheep with pine smoke inhalation through an endotracheal tube for 6 min. Arterial blood gases, HbCO, HbO2 and pulmonary compliance (Cdyn) were monitored, and the morphology of the tracheobronchial tree and pulmonary parenchyma were studied by light and electron microscopy. Severe carbon monoxide poisoning with fatal levels of HbCO (greater than 50 percent) was found at the end of smoke inhalation. Acute respiratory distress, progressive hypoxemia, decreased pulmonary compliance and increased P(A-a)O2 and Qs/QT occurred after injury. Tracheobronchial blockade by pseudomembrane cast, pulmonary edema, atelectasis and necrosis of pulmonary epithelia were demonstrated pathologically. The mechanisms of CO poisoning and ARF are discussed.

Abstract
Chronic lung lymph fistulae were produced in six goats according to Winn's and Stothert's methods with our modification to define the pathophysiology of pulmonary oedema after severe steam inhalation injury. Arterial blood gas, lung lymph flow (QLym), lymph/plasma total protein concentration ratio (L/P), and beta-glucuronidase (beta-G) in plasma and lung lymph were monitored for 24 h post-injury. The pathological changes in the lung tissues were also determined at the end of the study. It was found that directly after injury, QLym increased steadily to a peak value at 6 h, followed by declining values at 18 and 24 h. L/P decreased promptly during the 60 min after injury and then also steadily increased to a peak value at 4 h (P less than 0.05). A significant increase in plasma beta-G was only observed at 4 h post-burn. However, lung lymph beta-G activities and lymph beta-G transport increased immediately after injury, reaching a peak at 4 h (5 and 12 times above baseline values, respectively, P less than 0.01). Significant hypoxaemia and hypocapnia occurred at 2 h post-burn and deteriorated progressively throughout the study. There were obvious pulmonary interstitial and alveolar oedema microscopically. This study demonstrates that the increase in transvascular fluid and protein flux after steam inhalation injury is mainly due to increased pulmonary microvascular permeability. Nevertheless, a hydrostatic pressure effect can not be completely excluded, especially in the first hour post-burn. Lysosomal enzyme release is considered to be one of the important factors which damage lung microvascular elements and induce an increase in their permeability.
