The present paper is the second part of a series of papers on the ncmatodcs of donkeys in Peking. Eight species belonging to the family Trichonematidae are reported, namely, Trichonema labratum, T. labiatum, T. labiatum var. digitatum, T. coronatum, T. longibursatum, T. mimttum, T. tsengi sp. nov., and Petrovinema peculation.Trichonema tsengi sp. nov.A moderately small species. Male 6.4-7.6mm; maximum breadth 0.275-0.345 mm. Female 6.6-8.4mm; maximum breadth 0.275-0.36mm. The anterior extremity tapers slightly to the head; there is no definite neck. Mouth collar moderately high and is marked off from the rest of the body by a constriction. Circumoral papillae projected forward and are as long as the external leaf-crown. The external leaf-crown composed of about 18 long pointed elements, projecting well beyond the mouth collar. The elements of the internal leaf-crown are about 36 short refractive rods. The region of origin of the elements of the internal leaf-crown extends back to 0.005 mm behind the anterior border of the buccal capsule. Buccal capsule is general long and is somewhat narrower anteriorly than posteriorly. It has a depth of 0.037-0.046 mm in the male, 0,038-0.048 mm in the female, with a maximum breadth of 0.032-0.036 mm in the male and 0.033-0.038 mm in the female at its posterior extremity. The walls are thick and swollen at the posterior end and decrease in thickness anteriorly. Dorsal gutter well developed, and projects far into the buccal capsule, extending nearly to the level of the anterior fourth of the buccal capsule. Length of the oesophagus is 0.276-0.348 mm in the male, and is 0.314-0.407 mm in the female. The breadth of the oesophagus is 0.057-0.067 mm at the anterior extremity, and the greatest breadth is 0.081-0.101mm.Excretory pore and cervical papillae are at about the same level behind the nerve ring, and are 0.247-0.379 mm from anterior extremity. Distance from the extremity to the nerve ring is 0.18-0.23 mm.Posterior extremity, male,-fairly long median lobe; lateral lobes marked off from the dorsal lobe by a shallow notch.

Photometric observations of Nova Her 1963 were started in Peking on Feb.18, 1963,with a photoelectric photometer mounted on a 15 cm aluminized Cassegrain reflec- tor.The Nova was observed in the ultraviolet,blue,yellow,and red as well as through four relatively narrow-band filters whose commercial type designations being S43,S47, S50 and S53,with maximum transmissions of the cell-field lens-filter combination at about 4300,4550,4850 and 5230(?) respectively. Table 1 lists the types and parameters of the filters.Figs.1 and 2 show the response curves of the cell (an unrefrigerated type EMI 6256 B tube) field lens combination when used with various filters as determined with a reflecting monochromator.The zero- point drift of our amplifier and the linearity of the amplifier-Dahua recorder combination are presented in fig.3. The star a=HR 6845 served as the principal comparison star,while μ Lyr and later c=HR 6853 was used as the check star.An attempt was made to reduce a part of our observations to the U,B,V-system using extinction and transformation equations in the form of equations (A),(B) and (C).u,b and y denote ultraviolet,blue and yellow magnitudes out of the atmosphere on our instrumental system,while u′,b′ and y′ denote the corresponding magnitudes inside the atmosphere.X is the air mass.The k's are extinction coefficients and the A's are transformation coefficients.Observations of selected U,B,V-standards were made on 10 nights in a manner after K.Serkowski. Narrow-band extinction observations were made on a single night by following γ Lyr through various zenith distances,from which a magnitude-air mass plot was obtained as shown in fig.5.The relation between the extinction coefficients so obtained and the maximum transmission wave lengths is shown in fig.6. As part of the discussion the probable errors of a single observation and that of the mean valuc of the natural magnitude differences in four colours (r=red) between c and a are listed in the third and fourth rows of Table 6,while a comparison of our U,B,V- data of a and c (second row from bottom) with those of other observers may be seen in Table 7. Tables 2—3 list the magnitude differences (Nova minus a) without differential ex- tinction correction,where ‘43’,‘47’,etc.denote observations through the filters S43,S47, etc.,and the values followed by colons represent uncertain results.The Nova entered the “transition” stage during the interval April 1—10,1963. A plot of magnitudes against log t (t being days after light maximum) as shown in figs.7—10 leads to values of t_c (t_c denotes the value of t at the points of intersection on these figures) increasing with effective wave lengths as indicated in table 4. For the star a we derived the values V=5.57,B-V=-0.15,and U-B=-0.42, each with p.e.=±0.01. Table 5 lists U,B,V-values of Nova Her 1963.The variations of V,B-V,and U—B are shown in figs.13—14.On the two-colour diagram (fig.15) our observations show the Nova moving in an extremely complicated manner,yet with a tendency first moving to the left downwards and,starting from early April,1963,moving to the right while down the diagram.It should be noted that large systematic differences exist be- tween our (B—V) values and those of the Italian observers,amounting to about 0(?)6,which could scarcely be explained by observational errors or by a strange behaviour of the Nova colour fluctuations keeping pace alternatively with the observations in Pe- king and at Asiago.Large differences of about the same order of magnitude seem also to exist between Babelsberg and Crimean(B-V) observations of Nova Her 1960. The situation seems to favour the point of view advanced by the Babelsberg observers that meaningful colour measurements of such abnormal stars as novae are impossible with ordinary wide-band photometry such as using the U,B,V-system. Adopting M_(V,max)≈3 and the date of maximum to be Jan.31,1963,one could make use of a relation to obtain an estimation of the visual absolute magnitude at maximum of Nova Her 1963 to be about -7.6,whereby we used the value t_(3.V)≈38 days according to our light-curve.In addition our observations show the Nova to be a fast one according to the classification listed by C.Payne-Gaposchkin.

1. After oral administration to rabbits and man, Funacillin was absorbed mainly in the small intestine and very slightly in the stomach and colon, reaching its peak concentration in the plasma in 4 hours, and then declining rapidly; a single dose (200 mg/kg body weight) given to a rabbit orally yielded in 4 hours a level of about 14 μg/ml and then a trace only at the end of 12 hours. 2.After absorption, Funacillin was distributed throughout different organs, as liver, brain (cortex, midbrain and brainstem),...

1. After oral administration to rabbits and man, Funacillin was absorbed mainly in the small intestine and very slightly in the stomach and colon, reaching its peak concentration in the plasma in 4 hours, and then declining rapidly; a single dose (200 mg/kg body weight) given to a rabbit orally yielded in 4 hours a level of about 14 μg/ml and then a trace only at the end of 12 hours. 2.After absorption, Funacillin was distributed throughout different organs, as liver, brain (cortex, midbrain and brainstem), spleen, lung and kidney with varying degree of concentration which was highest in brain and spleen, the time of reaching its peak concentration in organs coincides with that in plasma. In the rabbits, whose liver function was damaged by carbon tetrachloride, the peak concentration in plasma was no higher than that in the normal rabbit. Ligation of the common bile duct caused a decrease in its concentration in plasma. 3. When incubated with slices of liver, brain, intestine and kidney, for 1 hour, Funacillin was not quantitatively recovered, because a certain amount had been decomposed by the tissue slices, particularly the liver. 4.Funacillin was excreted through the urine only in small amount (1—5% of the original dose). 5. Artificial pyrexia produced by subcutaneous injection of E. Coli vaccine to cats, was not abolished by Funacillin. 6. No demonstrable effect was observed on the blood pressure and respiration, when Funacillin was given intravenously to rabbits. 7. Funacillin did not prolong the anesthetic time of Evipan.

人和兔口服呋喃西林后,易从胃腸道內吸收,吸收的主要部位是小腸。給药后4小时血浆浓度到达最高峯,以后迅速下降。总胆管結扎后呋喃西林由胃腸道吸收显著減少。呋喃西林被吸收后,能分布至主要脏器內,其中以脑及脾脏中含量最高,极少量以原形由尿排出。体外試驗,呋喃西林与多种組織一起培养,即被分解。以四氯化碳損伤兔的肝脏功能后,不能提高呋喃西林在血浆中的浓度。呋喃西林对血压、呼吸、环己巴比妥鈉麻醉吋间无甚影响。且无退热作用。
