In the pig resource population, the average informative meiosis (IM) was 217.4 (44–316), and the average linkage map length between the two sexes on the five chromosomes were 172.3 cM (SSC4), 168.7 cM (SSC6), 191.7 cM (SSC7), 197.3 cM (SSC8), and 178.3 cM (SSC13).
Three thrombin inhibitors, α_1AT, α_2M and AT-Ⅲ, in neonatal period were measured. Their levels were 2.834±0.551g/L, 4.470±1.056g/L and 0.195±0.053g/L respectively (with activities 43.5±12.3%). No significant difference was found between two sexes.
[Methods]473 college students were randomly selected to be surveyed on attitudes in five respects of the communication between two sexes in questionnaire.
It was found that the side of a whorl of which the ridge count was enumerated was highly correlated with the type of orientation of whorl pattern, association analysis indicating p<0.001. The a-b TRC was 38.05±4.63 in males, and 38.05±4.54 in females, being 38.05±4.58 in average. There is no significant difference between two sexes (p> 0.1).
As to the patients with complicated blood stasis, there was no remarkable difference (P>0.05) between two sexes, but there was an evident difference between the cases of 0-5a course of disease group and the cases of over 5a course of disease group, and cases increase with the course of disease.

②The umbilical blood lead level of 128 neonates was (0.17±0.13) μmol/L, which was(0.17±0.12) μmol/L in males and (0.17 ±0.15) μmol/L in females, and there were no significant differences between two sexes (t=0.65 P=0.54).
T and E_2 rise with age increasing, however,the rises of T in male and E_2 in female became significant from aged 10.There is also obvious difference of F_0 between two sexes from the same age;
In our series, the incidence of males was 81.08% and the incidence of females was 87.66% and the difference between two sexes was not significantly significant (P>0.05).
We studied female copulation solicitation in the pied flycatcher Ficedula hypoleuca in aviaries where the two sexes were physically separated by nylon netting so that the males could not mount the females.
Fat physiology and biochemistry differ between the two sexes.
Lung cancer is the most frequent cancer worldwide, accounting for about 12% of all new cancer diagnoses in the two sexes combined.
Increases are similar in the two sexes and have followed a clear cohort pattern, paralleling changes in smoking habits and cigarette design more than diagnostic advances.
The pheromone of Trogoderma granarium males was subjected to two bioassays intended to examine its effect on the two sexes of the species.
The phrenic and accessory phrenic nerves of 180 cadavers of Chinese children were studied.It was found that the highest rate of the accessory phrenic nerve may be up to 73.8%.There is no significant difference between the two sides or the two sexes.The branches of the accessory phrenic nerve vary from 1—4,among which the single branch type is the most common one (76.1%).They have their origin from C_3 to C_(4—6).A few of them may arise from the ansa hypoglossi and supra- scapular nerve.Accessory nerve,therefore,is...
The phrenic and accessory phrenic nerves of 180 cadavers of Chinese children were studied.It was found that the highest rate of the accessory phrenic nerve may be up to 73.8%.There is no significant difference between the two sides or the two sexes.The branches of the accessory phrenic nerve vary from 1—4,among which the single branch type is the most common one (76.1%).They have their origin from C_3 to C_(4—6).A few of them may arise from the ansa hypoglossi and supra- scapular nerve.Accessory nerve,therefore,is more related to the brachial plexus rather than the cervical plexus.It was found that there is a close relationship between the origin of the accessory phrenic nerve and its positional and connectional relation with its main trunk.The nerve originated from the brachial plexus and its branches is located at the lateral side of the main trunk and usually forms a lower connection with it.That comes from the cervical plexus and its branches is usually located at the medial side of the main trunk and forms a higher connection (above the subclavian vein,35.9%) with it.The accessory nerve comes from the lower part of the cervical plexus and upper part of the brachial plexux is at first located at the lateral side and,finally,after crossed over anteriorly or posteriorly,joins the medial side of the main trunk (posterior to the subclavian vein, 7.8%).Based upon the number of branches,the phrenic and accessory nerves can be grouped into 5 types.The tirst type that is with the phrenic nerve proper alone,(43.1%) and the second type that is 1 phrenic nerve and 1 accessory phrenic nerve (43.3%) are the standard types in the Chinese.
Observations on the flight duration and wingbeat frequency were made in thelaboratory at various constant temperatures and 65--75% relative humidity. The mothsused consisted of individuals emerged from pupae collected from the field and rearedin insectary. The results obtained indicated that some individuals of the moths can fly continouslyat 17℃ for 36 hours. Fig. 4 But the duration of flight varied with the insect age. In themoths one day after emergence it was shorter as campared with those of older ones.The...
Observations on the flight duration and wingbeat frequency were made in thelaboratory at various constant temperatures and 65--75% relative humidity. The mothsused consisted of individuals emerged from pupae collected from the field and rearedin insectary. The results obtained indicated that some individuals of the moths can fly continouslyat 17℃ for 36 hours. Fig. 4 But the duration of flight varied with the insect age. In themoths one day after emergence it was shorter as campared with those of older ones.The longest duration has been shown by those moths aged 3--4 days. Most of thefemale moths 5 days after emergence had fully developed ovaries, and their flight dura-tion dropped down rapidly. This fact suggests that the period before sexual maturationwould be the optimal time for the insects to carry out long distance migration. Nutrition and environmental temperature would influence the flight ability of themoths; the flight duration of the moths under starvation condition decreased apparently;and at lower temperatures it will be prolonged (table 2, 3). The wingbeat frequency varies with the age of moths, as shown in Figure 1. It isworth while to note that the difference in frequency of the two sexes increases with age,and fluctuates slightly with temperature within the range of 25--30℃, beyond which theinfluence of temperature on wingbeat frequency becomes apparent. Light or sound stimulation may affect the flying behaviour of the armyworm moths.Flash light or sound may initiate the flight of the resting moths (Fig. 5A, 6A) or causethe wingbeat frequency of flying moths to increase temporarily (Fig. 5B, 6B), with afactor of 6% for light stimulus and 8% for sound stimulus. They also cause the ampli-tude of wingbeat to increase temperarily (Fig. 7). The latent period of these responsesdre 0.08 and 0.09 second for light and sound stimulation respectively.
Methods of identifying the sex of eels at the seaward migrating period were studied.Expernal characteristics,by comparing the diameter of eyes,interorbital space,the shape of snout,etc,are sufficiently reliable for the identification of both sexes.These morphological dimensions when calculated with the aid of distinguish function,confirm the differences between the two sexes.Consideration of morphological dif-ferences of the 400—600mm size group,permits separation of the sexes with 90 percent accuracy.Plotting...
Methods of identifying the sex of eels at the seaward migrating period were studied.Expernal characteristics,by comparing the diameter of eyes,interorbital space,the shape of snout,etc,are sufficiently reliable for the identification of both sexes.These morphological dimensions when calculated with the aid of distinguish function,confirm the differences between the two sexes.Consideration of morphological dif-ferences of the 400—600mm size group,permits separation of the sexes with 90 percent accuracy.Plotting of size distribution separates naturally one sex from the other.Those above 600 mm are nearly all females,and those below 400 mm are almost allmales.The relationship between length and weight of both sexes may be expressed asⅣ=0.0000001285L~(3.015).The regression coefficient of these two variates of eel between400—600 mm in body length is different for male and female.The former is 0.887(W=0.887 L—280.20),and the latter,1.150 (W=1.150 L—376.73).In the caseof the condition factor,the male s found to be 1.15±0.052,the female 1.42±0.053.Differences of both figures are significant.
