[Composition]
The main component of this
preparation is human immunoglobulin, which is prepared by cold ethanol
fractionation of human plasma from healthy donors. The manufacturing process
contains a step to remove anticomplementary activity and a dual viral
inactivation process. It contains a suitable amount of glucose or maltose as
stabilizer (see table below), but does not contain any antiseptic or
antibiotic. The distribution of IgG subclasses is close to the serum level of
normal subjects and maintains the bioactivity of Fc fragment of IgG.
[Indications]
1. Primary
agammaglobulinemia, such as X-linked hypogammaglobulinemia,
common variant immunodeficiency diseases, immunoglobulin G subclass deficiency,
etc.
2. Secondary
immunoglobulin deficiency diseases, such as severe infection, septicemia of
newborn, etc

The unit should not run in the wind direction to prevent the unit from working properly; the air inlet on the side of the grain clearing organization should be adjusted to be smaller, and the air inlet on the leeward surface should be increased. The purpose is to reduce the loss of grain blowing and improve the quality of the grain.
2. Slope operation
Try to avoid cross-slope driving operations; when harvesting on long-distance slopes, you should increase the back of the sieve and use larger sieve holes. The inlet opening should be reduced to reduce food losses; when harvesting at short distances, you do not need to Adjustment; when harvesting long distances downhill, the back of the sieve should be lowered.
3. Wet field operation
When the harvester is operating at a low level, the harvester driving device should be converted into a tracked or half-tracked type to harvest crops in time; when the depth of mud feet is large, increase the unit's ground wheel width to enhance anti-skid ability and expand grounding as much as possible. Area to prevent the machine from sagging.
4. Falling crops
Appropriately reduce the unit's forward speed; correctly select the unit's harvesting direction, the unit's direction of advance should be opposite to the crop fall direction (known as the back cut), or 45 with the fallen crop. The angle between the left and right sides (called the side cut); adjust the forward and downward adjustment of the reel to ensure the smooth reeling and normal cutting.
5. Low crop operation
For proper adjustment and modification of the header and reel, the height of the header shall be kept at a height of 15 cm and the cutting knife will not eat soil. If the cutting is too low and the knife will eat soil, the knife wear will be accelerated. Accidental damage and damage, the reel will be adjusted downwards and backwards for proper harvesting; increase the unit forward speed to ensure the normal threshing feed; along the direction of the sowing line can reduce the increase caused by the advance speed The unit's strong vibrations also reduce harvesting losses.
6. Overdry, over-ripened crop operations
Adding canvas strips on the wooden flipper platen to increase the cushioning effect of the reel wheel in the reeling and reduce the loss of grain; reduce the height of the reeling wheel so that the reeling wheel does not hit the head of the crop to reduce the loss. Grain; Reduce reel speed to reduce the number of hits on the cutting crop.
